Segment length / radius should give you the angle in radians. The file you uploaded has 40.365 degrees between the close holes; my math lands at 39.4261degrees. 1.18699992 / 1.725 = 0.6881158956521739 radians or 39.4261366 degrees. I used the roll function to confirm, what am I missing?

Need Help With A Leadscrew
CNC_Newbie replied to CNC_Newbie's topic in Machining, Tools, Cutting & Probing
Looking all over I found info on leadscrews that almost matched up to mine. The info is as follows Its a 2 Start Acme thread .25”/.635mm lead, OD is .442”/11.23mm, root diameter is .325”/8.26mm. The overall length is 22-15/16” inches. It has a turn down on one end that is .625” from the end and OD is .312 (its drilled and tapped with a small button head cap screw). The other turn down is .800” from end with an OD of .375 - Today

Need Help With A Leadscrew

Some of the eBay screws will machine it to a print. Chinese though. With a 5 mm pitch you can microstep it 10x and get .0001" per step -
I don’t know the correct way to measure and order a new leadscrew. I did Google information on the subject, but I cant find anything that matches mine exactly. I made a short video showing what my leadscrew looks like. If anyone can offer me sone tips to get a new one ASAP

Try posting the feed rate on it's own line: pbld, n$, *scclgcode, *ng70s, *ng70e, e$ pbld, n$, pffr, e$ The buffer is handling the gcode and the start and finish line numbers. Looks like there are some flags set up to determine the "canned turning cycle type". Find lathecc to see list of flags.

Yup.. I bought my Quadro RTX 4000 in Dec of 2019 for $780 at Amazon.com I priced it last week and it was $1250 We just bough a new Boxx for one of my guys and they charged $515 to upgrade form an RTX 2000 to a 4000 I have a Quadro 4000 in my work machine and the newer RTX4000 at home There is a noticeable difference between the 2.. the RTX runs Verify much better than the old Quadro 4000

Force feed in G70
Wayne Schwarze replied to Wayne Schwarze's topic in Post Processor Development Forum
Thanks for the help, but this is exactly what I've already tries and where I'm stuck. I add the pffr to the line and try and trace the debug. I add a breakpoint to the line before the g71 and the g70 to see what's going on but the post is using strings and buffers for the g71 and doesn't show a whole lot when it comes to tracing. I seems like I need to add some buffers parameters before the G70 lines to get the pffr to post the correct callout. but for the life of me I cant seem to find the correct combination to make it do it. the butter parameters look something like this. sav_feed = feed sav_ipr = ipr_actv$ feed = sav_feedcc ipr_actv$ = sav_iprcc I believe this will force it to pickup the ifr_l feed output. -

I Need To Build A New PC
Matthew Hajicek - Conventus replied to CNC_Newbie's topic in Industrial Forum
From my experience and what I've read, a GeForce gaming card is perfectly fine, up to a certain size and complexity of part model. Above that point you need a Quadro. That said, good luck buying a halfway decent GeForce right now. The crypto miners and scalpers are buying them with bots the split second they become available, and that's even at 2X MSRP. I got a new system for programming at home a couple months ago, and found I was better off buying a complete system than building one. The video card alone would have been half the price of the whole system. Here's what I got; price has gone up $300 since I got it: https://www.newegg.com/hp-omen-30l/p/3D5-0005-00C08 -

In modern Mastercam the opencl implementation on the card also becomes important, so the graphics card should definetly support that.

As So not a Guru said Lathes are a bit different. Not my forte either... There is a pffr post block which forces feed output, and I can see that in the g71-73 output post blocks. However you are trying to set the feed rate in what is essentially the subroutine call line N4 G71 P5 Q12 U-0.01 W0.005 D0.08 F0.01 N5 G00 X4.5 N6 G01 X3. R.25 F.005 N7 Z-1.75 R.5 N8 X1.5 R.125 N9 Z-2.25 R.125 N10 X.75 R.125 N11 Z-3. N12 X0.73 N13 G70 P5 Q12 N13 in the above code I found this in the pread_g70 postblock: pbld, n$, *scclgcode, *ng70s, *ng70e, e$ You could try pbld, n$, *scclgcode, *ng70s, *ng70e, pffr, e$ but that will only output the current modal feed rate. So you might need to save the finish feed as a user defined variable and call it here. Running a trace in the debugger should show you what's happening more clearly.

Force feed in G70

I'm unfamiliar with Lathe, but it looks like the feed postblock variable that you would want to add the asterisk to is pfr. -
Force feed in G70
Wayne Schwarze replied to Wayne Schwarze's topic in Post Processor Development Forum
Thanks for the reply. I'm aware that an * will force the output. And I've tried that. But for some reason unless the finishing is directly following the roughing cycle it doesn't post out the feed. Or when I do add the *. It post out the feed rate for the rough tool and not the finish. This is the issue I'm having. -

An asterisk (*) before the feed variable will force MC to output the feed. -

Prompt for user to select Lines
[email protected] PISTONS posted a topic in Mastercam C-Hook, NET-Hook and VBScript Development
Hello all, After a computer crash I am being requested to recreate a net-hook to allow user to select a line from the MasterCAM display area. I have everything set up the way I want it but now I can not get the program to allow user to select the lines. The code looks like this: Module Selection_Tools Friend Function AskForLineGeometry(SelectionNumber As Integer, Total As Integer) As LineGeometry '// Ask user to select a mastercam line Dim Message As String Dim Mask As GeometryMask Message = "Select Line # " & SelectionNumber & " of " & Total Mask = New GeometryMask(False, True, False, False, False, False, False, False) Return AskUser(Message, Mask) End Function End Module In the Main Run command I initialize the Selection_Tools module and the actual call looks like this: Dim Line As Mastercam.Curves.LineGeometry For i = 1 To TotalLines Me.Hide() Line = Selection_Tools.AskForLineGeometry(i, TotalLines) LineLength = Mastercam.Math.VectorManager.Distance(Line.EndPoint1, Line.EndPoint2) Next When ran I get the user prompt i.e. Select line 1 of 10 but the mouse will not allow any geometry to be selected. If I click on the select prompt I can <esc> thru the for look but nothing can be selected on the screen. Any help on this would be greatly appriciated as I spent alot of time this weekend head scratching and I do not have much hair left to scratch out -

Hey everyone, I'm fairly new to post editing, and am trying to edit my Generic Hass ST 4X lathe post so it will force a feed rate to post on my G70 canned cycle line. The issue I'm having is many time my student use a roughing and finishing canned cycle to turn there part, then single point there thread, and like to come back over the thread to take off any burs that may have come up. Well when we post just the Finish canned cycle (G70) after the thread, it doesn't post a feed after the P100 Q110 lines, leaving the tool to feed at the last feed rate, which in this case is a treading reed(F.050 IPR). So all need to do is force the G70 to post a feed after the PQ for the tool its using. I can get the post to output a feed but it's using the feed from the roughing cycle, not the finishing cycle. Any help would be appreciated.

I don't know for certain that it is necessarily a "performance" related better option but it's most definitely a system stability better option. It's all about that OpenGL implementation that makes a card stable for CAD/CAM/CAE and very good for Mastercam. ATI cards are pretty much dog$#!+. A few people have had success with them but the overwhelming majority have had stability issues with them. On board video... 99% guarantee to be stability issues.

Colin Gilchrist taught me how to do a point operation in a free tutorial on his YouTube channel. Now I can put the tool wherever I want between operations to clear anything I need to.

Thanks guys

I'm not sold on this. Still looking for any performance related metrics showing Mastercams benefit from Quadro cards. (comparing equivalent VRAM spec'd cards) I guess if budget is of no concern, no reason to not get a Quadro. Though if you have to stay within a set price, I think you would get a better overall Mastercam system by taking the money saved by not buying Quadro and upping your amount of RAM, or stepping up your CPU, or increasing the amount of SSD storage, or getting more monitors.

Looking at your picture, Either your stock is defined incorrectly or a previous operation is cutting away the walls of the part. Mastercam looks at the stock that is left after an operation and will exit the part the quickest way. If you change things so that the stock updated correctly, the boring bar will retract without going through the wall. And Master Gcode is right. Reference points create a level of safety for approach and retraction.

Benchmark 3.0 This is a good place to start The thread was started 3 years ago.. so I'd check out the most recent couple of pages first A few points.. If you don't NEED a laptop, get a desktop .. you'll get much more bang for your your money Speed is king.. buy the fasted processor you can afford (i7 or i9) don't waste your $$$ on a Xeon. 16g of ram is the bare minimum 32 is better Quadro video cards are your first choice GeForce gaming cards second Do not even think about Intel graphics get a solid state hard drive ..the money you may save is not worth the time you will sacrifice every day.

Desktop will be less expensive.
