Thanks machine guy I will look into that tomorrow.

The post was purchased from In House. I can send it to our reseller and they will fix it but I'm trying to learn how to do it myself. I have low level post modifying skills. Thanks for your help.

Cathedral, I have correct coolant codes working now. The reason I was getting an M09 instead of M89 is because I had the box checked that said "first coolant off command shuts off all coolant options." Now the problem I am having is the post is turning on the coolant in the wrong place. Haas recommends the thru spindle coolant be turned on before the spindle starts but it has to be after the tool change. Here's an example of the code.

cathedral, Thanks for the info. I'm still messing with the settings. So far I got the M88 to work but it still posts a M09 to turn it off. I'll mess with it some more after I finish my part.

I'm using thru the spindle coolant for the first time on our Haas UMC-750 machine. The M88 code turns the thru the spindle coolant on and the M89 code turns it off. I am currently using X8 with a post I updated from X6. When I go to my coolant parameters page and select the drop down arrow for thru-tool the options are ignore, M08, and M09. These are the same options that come up under the flood coolant drop down arrow. I also searched my post for M88 and M89 but nothing comes up. I was hoping there was a way to make these codes available in the post and also have them show up on the drop down menu on the coolant parameters page. Any help is appreciated.

Been using X8 for a couple weeks now and it seems to be really stable software. By far the best version I have ever used. I still have some things to figure out but I'll never go back to a previous version now that I've had a taste of X8.

OK got it. Thanks for all the help.

In pre X8 versions of mastercam there used to be tabs on the operation manager for Toolpaths, Solids, And MBD. I can't find the tabs in X8 and need to regenerate a solid. What am I missing here. Thanks, Justin

Set the gap size to distance and enter number larger than the gap size. Usually the bigger your part the larger the number will have to be. Set the motion to follow surfaces.

Greg_J I believe this first started in MCX7 as a way to speed up verify for larger files. Some people prefer it that way. I personally do not like it but I don't think there is any way to change it. Maybe someone else can shed some light.

Ken In your parameters page look under miscellaneous values. Some posts are set up to give you different retract options using miscellaneous value 1. I would look there first.

We used Blaser Swiss-Lube for the past seven years and It always smelled like crap. As soon as a machine would sit for any period of time the coolant would start to smell. I think it has something to do with bacteria forming in the coolant because the oil that settles on the top cuts off the air supply to the coolant. Our solution was to switch to Hankserfers. It never smells and is a much better coolant in my opinion.

To get a rotation move from your post you must leave WCS set to top and only change your tool and construction plane. How are you setting up your tool plane. There are many different options. Also your origin should be the center of rotaion. If you have a file to share I can set it up for you and explain what I did.

We use DNC Professional and currently have fifteen mills. Ten of them are RS232 and we can DNC to all of them at the same time from one computer.

Josh, I apologize it has taken me so long to answer your question. So far we are really happy with the Haas UMC-750. We are only using it to cut aluminum. We have Mitsui, Makino, and Kitamura to machine harder materials. We also added the 12,000 RPM spindle and a few other bells and whistles that increased the base price a little. For 5-axis aluminum work this is a very good machine for the price. I can't say how it will do with steel because we don't plan on using it for that purpose but I suspect the results would be poor compared to our other machines. In my opinion this machine is what it is a very good bargain for doing 5-axis aluminum work.

Thanks for the info everyone. I ended up shifting the G54 Z offset by .0035 and the machine is making good parts now. The reason I shifted G54 Z is because Haas include a tool with the machine that has a known gage length and diameter. The length of the tool is 5.000. I ran that tool on the machine tool setter using the length non rotating setting and the offset was .4.9995. I don't have any way to check the tool so I have to assume the tool really is 5.000 inches. I have a few jobs to finish then I will go back and recalibrate the tool setter and run the probe program that checks the center of rotation and see if I get the same numbers. One other questions I have been wondering about the tool setter is do you set a tool with a corner radius the same way you set a tool with a sharp corner. For instance if I want to set the length on a .500 endmill with a .125 corner radius using the length rotating setting do enter .500 for the diameter of the endmill. I want to be sure the offset is being picked up from the flat on the bottom of the endmill and not a point somewhere on the corner radius. Once again sorry about the hijack. Let me know if I should start my own thread. I really appreciate everyone's help.

JeremyV I don't mean to hijack your thread but we just purchased a new Haas UMC-750 5-axis machine. A guy from Haas came out and setup up the machine. He used the probe to find the "machine rotary zero point" otherwise known as the center of rotation and then showed me how to use the tool probe. I set up a job and used the probe to set all my tools. All the tools seem to be cutting about -.005 too low in Z so my part thickness is coming out undersize. I'm trying to determine if the probe is setting the tool to low or the machine center of rotation is wrong. Any Suggestions? I would assume the tool probe would not be worn if it was brand new.

Thanks, Mastermind408 I will do the same.

Crazy, I forgot to mention that this is the Post from In House that is supposed to be dialed in. We have purchased many posts from In House in the past and we are always pleased with them. Most of them do require a few tweaks once you get them and start using them. When something needs to be tweaked that is above the scope of my knowledge we usually send the post to our reseller then they get in touch with In House and once In House makes the changes the reseller sends it back to us. I'm going to send it to our reseller tomorrow. Mastermnind408, I turned off the switches in the post for DWO and TCPC because we are programming from the center of rotation and machining from solid blocks of material with no previous machining operations done to them. The parts are located on the machine in the same place they are programmed from in mastercam and we machine them complete in one operation. We had a technichian from Haas come out and set up the machine. He ran the probe and entered all the numbers in the parameters for the Machine Rotary Zero Point. Since we are programming from the center of rotation we copied those numbers into the G54 work offset and now we can program parts from the center of rotation without ever having to probe anything or pick up a part zero. Like I say now the problem I'm having is the post isn't posting out the correct numbers that I have set in Mastercam when I use any tool plane other than top. On a side note I hear what your saying about the clearance issues with the platter. I designed a fixture that gets the parts up off the table. Once I get this post problem fixed I'm going to start making some parts then make adjustments to the fixture if needed. I'm glad to know you have the same machine. Let me know if I can be of any assistance in the future. We may both encounter some of the same issues.

Crazy thanks for the suggestion. I fixed the problem by making the following changes to the post. You can see the changes on the lines I initialed with #JB # Coordinate Formats # -------------------------------------------------------------------------- fmt "X" 2 xabs fmt "Y" 2 yabs fmt "Z" 2 zabs fmt "X" 2 xabs_top fmt "Y" 2 yabs_top fmt "Z" 2 zabs_top fmt "X" 3 xinc fmt "Y" 3 yinc fmt "Z" 3 zinc fmt "X" 2 xhome fmt "Y" 2 yhome fmt "Z" 2 zhome fmt 11 rotabs # JB WAS 2 CHANGED TO 11 FOR 3 DECIMAL fmt 11 tiltabs # JB WAS 2 CHANGED TO 11 FOR 3 DECIMAL fmt 3 rotinc fmt 3 tiltinc fmt 3 rotdelta fmt 3 tiltdelta I'm not sure if I need to make the same changes on the rotinc and tiltinc lines. Also this post is having another issue. If I post a toolpath in the top tool plane all of my Z values are correct. When I post with other tool planes the Z values are not correct. For example when B is rotated 5 degrees and I have my clearance plane set to absolute 10.500 inches in mastercam the post will post out 10.509. If I post in the front plane and I have Z set to absolute 2.000 inches in mastercam the post will post out Z 4.000 inches. I'm sure I have my mastercam file set up properly so it must be something with the machnine def, control def, or Post. As a test I posted the same file with a machine def and post that we have been using for a few years and it gives me the correct z numbers. I'm going to call our reseller tomorrow and try to get everything straightened out.

I'm trying to run my first part on our new Haas UMC-750 but the machine is giving me an alarm when the B-axis goes to rotate. I believe it is because my post is posting the B move with four places after the decimal point. Three places after the decimal point seems to work. The alarm is alarm number 386 Invalid address format. I tried looking in the machine definition, control definition, and post so I can change the setting to post three decimal places only but can't find it. Can someone show me how to do this. Here is the G-code that is causing the alarm.

Ok thanks again.

Thanks for the information machineguy I really appreciate it. Hopefully I'll get to tap some holes tomorrow.

Thanks Chris that was exactly what I was looking for.

Watcher, Thanks for the reply. Maybe if I explain how we use this machine you will understand why I don't want to use DWO except in very rare occasions. We have G54 set to the center of rotation. We run all of our parts from solid blocks of material that have no previous machining done to them except tapped holes used to bolt them to the fixture. The parts come off the machine complete with no secondary operations. The parts are located on the machine in the same position they are set up in Mastercam. I plan to have two fixtures that can do just about every part we will make on this machine. I designed the fixtures this weekend in Solidworks and will make them this week from drop off material we have laying around the shop. We also leave all of our tools in the turret so we don't have to set tools unless something very non standard is needed. The fastest set up you can do is the set up that requires you to do nothing so in this case even probing the part is a waist of time. I'm glad the machine has DWO and TCPC but I will not need these features 99% of the time. I just want to be able to turn them on and off as needed with a switch in the Post. One thing I am still confused about is how the machine will react if I leave DWO and TCPC turned on because currently we have G54 set to the same numbers as the Machine Rotary Zero Point that the probe picked up when we set up the machine. Thanks again for your input and I would appreciate hearing any further knowledge you have on this subject. I am new to Haas and I am trying to get this machine set up the same way the other machines in our shop are set up.
