Come on guys. Someone has to know the answer! It's been asked for years. Is there a workaround with a VB script?

General Mach Discussion / Hard wired Jog speed override.

« on: July 18, 2017, 06:24:19 PM »

I have found several posts where people have asked this question. I haven't found an answer yet.
I want to hard wire a button that will act the same as the "shift" key on the keyboard while jogging. I tried the OEM button 202 "feed override jog" with no effect.
I can hard wire all the axis to jog, but only at the slow jog rate. Anyone have the solution?

General Mach Discussion / What's the best way to implement dual X motors?

« on: July 14, 2007, 06:53:15 PM »

My application is a CNC router with two X rack & pinion drives. I can identify two solutions. Software and hardware. I am looking for the advantages/disadvantages of slaving another axis with the X to accomplish this (in Mach3). I am using a PMDX-131. I would rather slave two geckos off of the same channel on the PMDX and save the axis in Mach and PMDX for a second Z axis. Does anyone know if the PMDX buffer can drive two geckos in parallel? I would like to hear some pros and cons to both solutions.

I sent PMDX support an email late yesterday afternoon and by mid morning Steve Stallings had called to discuss the problem with me. Seems it may be a hardware issue and he asked me to return it to them for upgrading. He said at kernel speeds higher than 25kHZ the problem would get worse. And it did. I will have to wait till I have it back to see if the upgrade fixes the problem.
