Subject: mach3 jogs fine but stalls when running G-code

I am trying to finish a CNC 3 axis router and am having issues with Mach3 current rev.

My setup is as follows.

KFlop board

KStep board

Windows XP pro

Mach 3 R 3.043.066

KFlop ver 4.32

3 axis with "A" slaved to "Y"  open loop normal stepping

All motors are nema 34, 200 steps / rev 

Motor tuning is V=3000 A=30000 J=300000 in Step Response.

16,598 pulses per inch

All that is loaded on Reset is the init C-Code

Pulse width is set to 4 uS in the standard C-Code

Axis A = -1 In the C-code (1,2,3,-1)

I made G-Code that is a Box that runs the parameter of my machine multiple times.

When I run the G-Code in DynomotionCNC everything runs perfect at 90 in/min. I ran this at least 20 times and each run lasts about 10 minutes with no fail or missed steps per marks on the gears. A axis is not bolted to the gantry but has a alignment mark that I verify on all "Y" axis moves. 

Using the same setup for Mach3, I can Jog the X and Y axis and all is good.

When I try to run the G-Code it Stalls immediately. I tried changing the motor settings in Mach to 30 in/min and changed the G-Code to match and it still stalls when start is pressed.

I checked the tutorial for Mach3 setup for Kflop and Mach3  and could not find anything.

What is the difference jogging vs running code?

Hi,

Mach3 GCode uses the Acceleration in the "Config | Motor Tuning" where continuous Jogs use the Acceleration and Jerk setting in KFLOP.

What is your Mach3 Motor Tuning Acceleration set at?

Mach3 motor settings
counts/inch 16,598
velocity 30
accelleration 100

I assume that Mach3 configuration is in inches?

If so 100 in/sec2 would be very high acceleration. KFLOP is set to less than 2 (seems low).

HTH

That was it, thanks Tom
She runs like a top.
