We've got a vf2 & vf4 and we're trying to use MCXstart to send a large file using dnc for the 1st time with no results. Keep getting " 232 buffer overflow. I've check the forum search, and there is nothing. I've tried different settings on the machine and computer, making sure they match, and still nothing. What are we doing wrong??? Thanks

Tried it. Feed 1.5 Spd 200rpm got chipload of .0025 and the spindle load went through the roof, almost redlining

So if I bump up my feed, and leave the spd thank should solve it??

reading .0012

the chip load on the display is ready .0012 (our mill HASS VF-4)

were running at 200 rpm and feed 0.7, I'm not a machininst ,but this seemed to work with little squeeling or vibration (thats what the boss wants to see)

we're using an ISCAR 2" Helimill E90AC, but before that were drilling a 13/16 through gole the a DR drill

Hey: we're doing 2"dia. countersinks 1-3/4 deep in some 2" thick AR400 wearplate. We're using a 2" indexable endmill. We're ending up with a big rats nest on the mill after everyhole and have to stop the VF-4 after every hole to pull it off before we continue.I was told not to peck or chip break with this tool. But what we did try was a 5 second feed hold after every .100" of depth which seemed to work great. Is there somewhere in the MCX drill cycle where I can get it to dwell for a couple of seconds at depth incriments , Or is there another way that I'm missing. Thanks

Printing this was my plan from the beginning, so the more feed back the better Thanks

His word against mine.......Sorry for the spelling.. I'm just so pissed my hands are shaking!!!

Your right I agree. I'm a welder by trade and a computer gooroo who picked up mastercam and programming skills along the way. Macining is new too me which is why I researched everything as I go. The problem Is a machinist who doen't like to do production, and likes one'zee and two'zee jobs, convincing my boss the job is to hard. His work against mine. I apologize ahead of time for the venting....I needed to unload somewhere...this seemed like a good place.

Money is not the issue. The job was quoted fairly and we are making good money. I too am convinced the machine can do it and I did my homework, and got the tool suppliers involved before I even got the job.

I appreciate the feedback... the more ammo on my side the better.. because ultimately I quoted the job I got the order, and he'll make me make the call to the customer. thanks

I'm currently doing a job, and our machininst has convinced my boss to pull the plug on it because he doesn't think our machine can handle it. I do the programming and pathing, and I think they're both wrong, and need some advice. We have a Haas VF4 vertical mill. The job we are doning is simple. I have 4000 holes I have to drill and counterbore in plates ranging from 1" - 2" thick. Material is 400AR wear plate (48BHN from what I've read up on) The 1" plates( we are doning now ) have a 13/16" through hole with a 3/4" deep counterbore.The other plates are the same , just a deeper counterbore. I had my tooling supplier come in to help me setup tool selection, speeds and feeds for optimal machine setting and this is what we are running at based on his recommendations. Drilling using 13/16" DR indexable drill Feed 4.0 rpm 1620. The counterbore using a 5/8" stub verimill, contour ramp, ramp motion "depth" , depth .125" Feed 9.0 rpm 1320. We also tried pocket with .375 step down , 50% tool width Feed 10.0 rpm 1420. Theres some vibration throughout the machine, but we're so used to cutting alumninum and other soft materials, and not the hard stuff , don't know if this is normal, Boss doesn't think so and wants to kill the job. All I need to know is , Is this machine capable of handling a job like this with this material or not. I've called our Haas sales rep and he hasn't returned my calls and doesn't seem like he is interested in helping out now that the sale is complete. Sorry for the story. Need direction Thanks

What about speeds and feeds??

Hey Guys.. I'm quoting on a job that requires us to counterbore 2" dia. holes 1-1/2" deep into liner plates with 400 BHN min. I'm used to aluminum and mild steel on our mill, and not really familiar with speeds/feeds for hard steels. Any recommendations for speeds and feeds, so I can run an acurate backplot for the quote. I have 2000 holes to do.Also what tooling recommended. Thanks Gus

Sorry my fault.... I meant to say I'm doing a lathe thread toolpath in MCX not threadmill

We're doing it in a HASS SL30 lathe with MCX, but I've never done anything that wasn't a standard thread I could just look up in a chart. Those #'s you gave me I think were exactly what I was looking for. Thanks

Hey: need some help please. I've got a brass fitting I'm working on, and on the one end, I need to cut some inside threads to fit on a standard garden hose. I've never used threadmilling in MC and could use some help on the settings to get that particular thread. Any help would be appreciated.

Thanks that worked, now im dealing with an X overtravel in the same lines hopefully we can fix. thanks again

We are using a bar puller for the 1st time on our Hass SL30 lathe and not getting anywhere.We keep getting a Spindle not turning error,but obviously we don't what it to turn. Here's what we are using. Any Answers???? (tool-3 offset-3) G00 0303 M05 G00 G54 X2. Z-2. G01 X-.500 M11 G01 z-.290 M10 G28 M05 M30 % I've also tried some MCX samples with bar puller and get the same result..

My employer is getting me a new office desktop, and it comes with an 256mb RADEON X600 card.... Is this going to ge OK for MCX???? reply asap,he wants to place the order with DELL today.. thanks

Crazy, thanks for the insight...makes perfect sense, and we tried it, moving the M1 or eliminating it, and its fine now. thanks

We've got a new VF4 HASS machine and purchased the hass post, and using Mill level 1, just purchased as well.

Just wondering... Why is it during some of our machining, our mill goes and gets the next tool ahead of time while the previous process is cutting, and other times we have to wait for the machine to go get the tool after a process??? Is it in the programming or something else...??
