General Mach Discussion / Re: Strange slave axis problem

« on: June 07, 2012, 02:26:55 PM »

We're starting to lose production time now......I put a new motherboard and expansion card in and new G540.....still faults on pins 8 and 9.  We even remapped the keys incase there was a problem with the keyboard arrows and nothing changed.  Swapped around all the cables and all the steppers and swapped the port cable with the THC and still the Gecko faults. 

I still think its in Mach3 or the XML file......any one have any ideas?

I remapped the pins and the problem follows the pins (8 & 9)

well.....its not the parallel port cable.  We also went back to the old G540 with a new G250 driver installed and its still the same.  I am able to leave the A stepper hooked up without a fault light if I disable the slave axis.  As soon as I enable the slave to the Y and jog the table it faults.

It is possible that I have a bad Parallel Port or cable

Good idea but no dice.

We've been runnning this table for 2 years in a production shop with no issue until now.  In the middle of a job the other day the G540 faulted, we quickly diagnosed it to the A drive (slaved to Y) in the G540 (it was noticably burned and we thought it shorted from metal dust since the controller was REAL dirty inside).  I removed the A drive from the G540 and it came back to life and we limped along driving the gantry from one side.  I bought I new G540 (cheaper to buy one and get extra parts than to buy a new 250 driver) and we installed it today.  It quickly went to fault again.  We swapped all the cables and ran all the steppers on other drives to eliminate a cable or stepper problem with no change we desided to swap drives around in the G540 to see if the issue followed the A driver but it didnt.  

I said all that to say this.....the problem has to be within Mach 3.  If I disable the slave drive we don't get a fault and if I enable it and leave the stepper unplugged still no fault but once I plug in the A its fine until I try to jog the table then it instantly faults and it will do this on every combination of cable, stepper and driver.

General Mach Discussion / Long pierce delay

« on: June 30, 2011, 10:25:38 AM »

I'm having a problem with a delay in my pierce even when the pierce delay is set to 0.0 in Sheetcam.  I have a THC301d and it gets an arc ok signal immediately after the firing of the torch and there is still @ 2 sec of delay while no G04 Px.x shows in the code.  Anyone have any ideas?

I think what I need to know is wether I can combine the two profiles without having to manualy set up my ports and pins.

General Mach Discussion / Mach3 XML profile for G540 and THC301D

« on: October 29, 2010, 08:09:59 PM »

I've been using the G540 XML but now that I've bought a THC301D it is provided with a new XML.....which one do I use, are there G540 specific changes that I need to make within Mach 3 if I use the new XML for the torch height control?  I havent installed the THC yet, I just wanted to be ahead of the game if I had problems.
