Hi Gang can anyone give me a good starting point to set up the motion parameters in TCNC?
My X axis is giving me headaches, I've replaced the X Gecko unit thinking I'd blown it, but it's OK.
I get rapids of 160 ipm on Y but X doesnt want to cooperate.
It is considerably heavier, I was getting good movement but losing step. I know going too fast.lol.Triple checked the wiring too.
What I would like to know are some good settings to start with.
Like max. speed (HZ) 40000
max acc. (HZ) 30000
max start spd (HZ) 10000
pulse width (uS) 2
these are the settings I tried on my machine.Just X axis misbehaves and its running quite free although fairly heavy.

computer= 200mhz IBM
steppers #34 4.5v 1.4a sanyo Denki
48v ps (55v no load)
1/2 x10 acme rod
Gantry style cutting area 29" x 15" all metal construction using skate wheel bearings.
I've tried settings to 60000 doesn't make any difference to Y and Z
