This is not really LinuxCNC related but something I should have done years ago, 3D-printed T-slot covers. It makes it much easier to vacuum up all the chips of the table.

 

 

It took three iterations to get the profile right, here are the test pieces I went through.

 

Here is the complete set that I installed.

 

They are printed out of flexible TPU filament and took about 4,5 hours to print on a Bambulab P1S printer.

The 7I33 can just ..., not pin-by-pin as most newer Mesa cards can do.

 

Is there a better alternative to the 7i33- just in case?

How can I get the spindle indexed?  Setup at the spindle is different- the motor encoder (G5) is just wired to the amplifier and not accessible for me, but a second encoder for threading (G2) is driven by the spindle via a toothed belt (1:1)
Signals for G2 are similar to the axes encoder signals, Ua1/Ua1*, Ua2/Ua2* and the index Ua0 single (non differential)

Mechanical Setup:

 

Wiring of G2:

 

I have the spindle running with G2 as a feedback- this works fine but I will need the index for threading.
How can I manage this?   I tried to make the index visible in HAL Scope, but can not set the "index enable" (get an error message)

The encoder G2 is connected to the 7i33 as ENC02, as said works fine for spindle feedback so far.

# The Step signal for my machine is inverted. I tried to remove the inversion from the step signal, but than the Stepper don´t move at all. Does that make sense??

please check your Opto-Outputs, perhaps they are too slow for the short pulses. ?!?!

EDIT: and please add you config
