Hi All,
I know homing and soft limits are a common issue for most. I've searched and read almost all of the forums on these issue and yet I have problems with mine. I'm running a Mach3 Motion Card controller and servo motors with G320X gecko drivers. My setup works really well, the limits work, homing works, and I can start machining. However I can't figure out the following issues as it really bugs me, I've worked on these for dayssss!
About my machine:
- Servo motors
- 5ft x 9 ft table
- Dual stage (4 motors, x and a are slaved, 2 homing switches on x-axis for auto squaring)
Issue 1: Homing / Squaring gantry
- If I'm in the slave mode on (x and a axis), auto squaring does not work no matter how I edit the script for homing. Is there a command to disable slave mode, home it, then turn slave mode on again? I tried a DoButton that was on a forum and it does not work.
- The only way I can square my table now with the limit switches is the following way:
1) open mach3 profile that is in a non-slave format
2) Edited the scrip to:
DoButton( 24 ) ' this homes the Z
DoButton( 23) ' this homes the Y
RefCombination( 9 ) 'move x and a together
DoButton( 25) ' this homes A to make sure
3) after this, I switch back to the 2nd mach3 profile that turns on the slaving
This is working fine, but I think if there was a way to turn off slave mode with in one profile, home it, and then turn it back on would be awesome! Perhaps in the brain setup?
Issue 2: Soft Limits
- My table is setup as described in the videos and forums and the limits do work. However the slow zone does not work no matter what! It acts like a hard stop when it reaches the limit.
- Also, the reverse check button seems to do absolutely nothing!
- When soft limits are one, sometimes it locks the A axis and twists my gantry! When softlimits is off i don't have that issue...
These is what I've tried:
- Increase the slow distance up to 10 inches, thinking that it doesn't have time to slow down
- Decreased the slow rate down to 5%
I really appreciate any help I can get. Thanks.
