General Mach Discussion / Mach 3 and ESS , axis not going at the same speed g1 g0
« on: May 22, 2018, 11:17:59 AM »
Hello,
Just finished my 3 axis (Y has A axis as a slave) router 1200mm x 2500mm with HIWIN AC Servos 10000 pulses/rev encoders, and I am desperate because the axis do no go in diagonal neither in G0 and G1 (in g1 only at higher speeds) meaning that if a comand a G0 X500 Y500 THE X AXIS REACHES FASTER AT THAT POINT. All the steps per unit are set correctly. Simply can get the machine to go. Another problem is that the problematic axis Y does not stop when I press the jog button. I have tried to get different results by changeing the ESS frequecies but nothing changes.
IN ESSENCE THE AXIS DO NOT REACH AT THE SAME TIME AT FINAL POSITION
The x and z axis are working fine with 1000 steps/ unit (10mm pitch ballscrew) y and slave axis has also 10 mm pitch screw but with 2:1 reduction so it needs 2000pulses per unit.
Servos tuned ok, settings in motor tunning are ok
Please be kind and give me a hint I an stuck and the machine has to start cutting stuff soon.
Thank you!
