Slaving over a hot Pod
Greolt:
I am building a router that has R&P drive on each side of the X axis.
Although the Y and Z axis are not done the slaving in Mach through LPT has tested well on the completed X
So as Art has released a plugin for the Pod that has slaving I thought I would give it a go :)
One side of the drive is designated X and the other side A. Slaving is selected in Mach X to A
Motor tuning is set the same to both drives. Try to jog. No go. Just acts like it is stalling. (turns slowly, makes a lot of noise)
Tried all sorts of velocity and accelleration settings. Nothing works.
Deselect slaving and X jogs perfectly on its own.
What am I doing wrong. Something stupid I guess. ;D
Graham Waterworth:
Have you got the 2 motors running in the same direction?
Are they mounted mirror style or in parallel?
If mirrored they need to run in opposite directions.

Greolt:
Motors are set to run in the correct direction. They are not fighting one another.
Being R&P I can simply release the spring that holds the pinion against the rack untill rotation direction is set correct.
Incidently I could not simply toggle "direction low active" to reverse motor direction as you can when using LPT.
Had to physically reverse two motor wires.
Chaoticone:
Can you swap your motor wires at the drives? Make x=a and a=x. This might help narrow it down. Before you do that, have you tried the a axis with the x axis disabled?

When X and A is slaved together no go. When slaving disabled both axis jog perfectly independantly.
Of course I have disengaged one pinion.
Wire it back up to LPT and slaving works as it should.
Fairly certain it is not a mechanical, driver or motor problem. Just something to do with slaving with the Pod.
Thanks, Greg
