Novamill - Mach3

[Deck36]

Nothing internally has changed with the wiring, so some combination of pins/outputs and values should surely do the trick?
I'm not in a position, time or mind wise to tackle rearranging the spindle functions and it's controller right now.

I'm going to give up the fight and get someone else to make my parts before I go completely crazy with frustration and chuck the damned thing out of the workshop

Thank you for your help. Both you and m_c have been brilliant in your efforts to educate me.

So a long awaited update on my Novamill situation.

The day after my last post I took a call from Brian at CNC4U, where he made some suggestions to get me running again.
The one thing that helped most was to use a higher quality cable from the UC100 controller-pc. Seems there is a lot of stray EMF and cheap cables don't have enough shielding.

Combined with the help I've had here I was able to finish the project I was working on.
Once again my thanks to everyone on this forum.

That leaves me with just one issue; the limit/home switches don't work unless virtual limits are set. If I lose my initial datums for some reason (light smashing into the part) I have to start again because I have no references.

Activation lights in Mach3 show the X/Y switches working (no Z though) but when I reference the table just runs over the switches until it hits a hard stop and spins the leadscrews.

It was mentioned in a previous post that Novamill switches are inductive, so the question is; do I try to replace them with mechanical switches, or can they be made to work as they are?

My workaround idea is to add a pin or hole on the bed somewhere are a permanent reference. That way I can get back to datum if things go wrong.

Any advice would be welcome. Thank you.
