Homing setup

Post by RogerFroud » Wed Jun 02, 2021 8:41 pm

I've found the HomeMM_V8.c program and am about to try this with the X-axis since that's the only one I've got hooked up at the moment.

I've changed the AxisChannel to 0 and set the limitbit to 136 which is the KANALOG Opto input 0 for the X-axis limit switch.
However, I don't know what to set the encoder bit number to. I've attached the schematic for the KANALOG Encoder Adaptor which shows that the X-axis Ref goes to JP1.5 A1 and /REF goes to JP1.6 /A1
What bit number would that relate to in the CreateHomeTask(0, 0, 1, 1, 100, 400, 136, 0, 0, 80); procedure? I'm guessing 2 since it's the third one?
What bit numbers will the Y and Z be? Those go to JP1.13/14 and JP2.5/6. Those would be 5 and 8 if my reasoning is correct?

Hi Roger,

I wouldn't use that Program. It is quite complex in that it allows dynamic configuration for any type of homing for any type of system using a number of methods. Its simpler to configure a program for your specific case. See here.

In that case the Ref Signal should show up as Bit 2. In most systems an encoder index pulse is to be used in conjunction with a home switch first. In your case possibly not so treat the index input as the home sensor instead.
