General Mach Discussion / Constant pulse generation?

« on: April 21, 2016, 08:36:46 AM »

I've been doing some work with my 4th axis and rounding my stock takes forever via indexing. Is there a way to manually set a pulse stream so I can run my 4th axis constantly like a lathe and then run a normal program?

Have any of the new mach 4 updates added screw mapping yet?

I'm not talking about anything crazy for differences. What I'm trying to do is map my ballscrews on both axis. I found out that mapping will not work on a slaved axis (but what it will do is transfer the master axis correction to the slave). So while not the correct approach I'm trying to change the steps per inch to get as close as I can to duplicate the error for both the master and slave so correction will work for me.

Can you explain why? If they are different is the slaved numbers ignored or will something else happen?

Can I have 2 different steps per inch between the slave and master axis? Or will Mach 3 only duplicate the steps for the slaved axis?

Any update on this?

General Mach Discussion / Ebay 4 Axis USB CNC Controller?

Anyone used one of these cards with Mach 3 yet?

I'm looking to add a rotary axis to my router. Being I'm using all the outputs on my G540 right now figure this may be a cheaper router to control another axis.

General Mach Discussion / Has anyone here used screw mapping?

« on: November 05, 2012, 03:08:54 PM »

Has anyone here used the screw mapping function and provide some feedback? I've searched but came up with very little info on this feature.

I believe I have some error in my rack and tried to use the screw mapping function in mach 3. I bought a 35" DRO to measure the actual movement and mapped my X axis. Once mapped I tried to run a program and it resulted in missed steps and the X axis double backing on itself in a straight line move along the X axis. So I then turned off the screw mapping and ran the same program and everything ran fine.

The screw length defaulted to 1300 (I'm unsure what unit of measure this is I tried entering my screw length in an inches value first being that's what I use defaulted in mach 3 and then I also used a value in mm) I can't figure out how to save the screw length. I've tried multiple times and it always defaults back to 1300. Does mach 3 pull this value from somewhere else? If so where and can I change that?

The second problem I believe is self induced where I entered the wrong value and saved it as a data point but then I corrected it with the correct one after that. (hey entering 200 points your bound to make a mistake) It was easy to see if I entered it wrong usually because I was an inch off of the correct measurement and the screw map went sideways, once i entered the correct number the map leveled out.

General Mach Discussion / Screw mapping a slaved axis?

« on: October 24, 2012, 09:51:52 PM »

I have a 4'x4' router with the gantry driven on both sides via rack and pinion. I'm thinking about mapping my rack and was wondering if there is a way to map my slaved axis? All I see in the screw mapping is for XYZ axes only. My guess is that being its a slaved axis that mach 3 would not compensate for it anyway.

General Mach Discussion / Homing question

« on: October 20, 2012, 05:41:43 PM »

I have a router with a motor on each side of the gantry (Y axis on the left and A axis on the right) and want to use 2 home switches to auto square the gantry. My question is lets say I find that my gantry is not square and I want to adjust the Y by .005 is there away I can adjust that in mach 3 to do a move instead of moving my Y axis home sensor? I was trying to use the distance off switch but any number I put in there just changes the DRO and does not actually move the axis.
