I am having a bad problem with lost steps, and was wondering if a second DRO display for the Y axis. Am using Y Master and Y slave.
The lost steps are always coming from the Y slave driver to the left side Y stepper motor.
If I switch the cables to the steppers, send the Y slave driver output to the right side stepper, the right side stepper starts loosing steps.
This looks like it points to the driver, and not the stepper motor.
What could be the cause of loosing steps?
The below test was ran Wednesday morning. Tuesday afternoon it was not possible at all to run the same code at 75IPM without it failing and loosing steps.
I was surprised this morning for it to run so well until later in the test, and I realize thet 200 IPM is extreme for me.
Here is some testing I have done at different speeds.
Material 3/16" plywood, 1/8" single flute end mill, cutting 0.050" per pass, the letter outline I'm cutting is 12"x14"
Test 1 pass 60 IPM
Test 2 pass 60 IPM
Test 3 pass 75 IPM
Test 4 pass 75 IPM
Test 5 pass 100 IPM
Test 6 pass 125 IPM
Test 7 pass 150 IPM
Test 8 pass 175 IPM
Test 9 fail 200 IPM Realign gantry
Test 10 pass 75 IPM
Test 11 pass 75 IPM
Test 12 fail 75 IPM Gantry skew left 33" right 34 3/4"
Stepper temperature left 170 F right 185 F
