I have been using Mach for 3 years now on many machines I have built three Hotwire, 3 Router tables and 1 and a half water jet, the half is the one that's eating me starting at my brain.
Here's the problem I have a industrial PC (from China) It's got a built in Keyboard and flat screen LCD PC has On board Video and the parallel port is out putting 3.3v but I have a C10 breakout board. All of the inputs and relay outputs are working fine. I have the A is slaved to the Y axis with matching gear rack, motors, gears, drives (Y and A have separate drives) I'm using G340s (Step multiplier x 5) with 500 Cnt Encoders. on 50:1 Planetary gear boxes so I need 5000 steps per rev. and 150 Vel, and accel 30 Motors were tunned with a Oscilloscope with a pulse generator at 40 msec pulse rate
Checked, double checked, Constupid checked the Configuration I had the kernel set at 25k and increased it to 45k in which improved when it was set to 25k if I hit the arrow key for x axis jog the A axis jogged roughly and error-ed out the G340s after 1/4 th of an inch of travel, Y axis jogging moved the X and Y and error-ed out the Geckos after and 1/8 th of an inch and racked the gantry. I had a G100 on this but had too many conflicts with the Chinese computer.
But now I'm at wits end. I have the following in the XML file:
Axis Port Step Pin Dir Pin X 1 2 3
Y 1 4 5
A 1 6 7
As I said I get complete limit, E-Stop, and Input#1 checking good.
I have a PCI 32 bit multi I/O parallel port card coming from
http://rogersmachine.net/PCIport.html but what else could cause such a problem, Oh I forgot to mention that I was jogging on 5% of 150 inches per minute when it was wigging out any higher and it errors instantly.
I'm posting the xml file.
