I'm sure the wiring for the brass puck is in the manual. It's just shorting the circuit - you'll not blow anything. Measure the depth of your puck with a micrometer and input that in Vpanel. I think it was 15mm as default? I guess you never received the last private message - it seems to be stuck in...

It's just a brass/metal puck with a known depth that earths when the endmill touches it...

From memory - it's an ordinary everyday 3.5mm jack.

I'll see if I have any photos.

messaged you a photo but seems to be stuck in my outbox...

I think you're right...

A rash 3 minute decision indeed! After a quick read through the forum you'll notice that everyone on the forum actually goes out their way to be very helpful. I guess, you being a software engineer, you're not into a bit of banter?

I hope you're not 59 by the way - that would be a bummer...

Ha, Ha! Not the one that just sold on Ebay? That was a premium price!

I'd definitely look elsewhere if you're main material is going to be aluminium...

At the end of my tether with this. There must be a solution to engraving uneven surfaces. By uneven I don't mean bumpy I mean a gentle variation in surface height. What ever happened to the ZCS-1 piezo sensor? I can't justify a new machine when this one works so well at everything else. Looks like I...

Always worth asking - it might have been easy. Not that anything is every easy.

It could have been that the voltages going to the spindle were translatable to the engraving head...

Is there any way to retrofit an existing machine with a MPX-90 head?

Yes I do want one machine that does everything

Any suggestions for motors that can so this?

I'm not sure what you mean? Would a different motor react faster? Lets pretend I am cutting fresh air. I'm just wondering how quickly a motor can respond to a speed change maybe between 9000rpm and 10000rpm and back again on each line of code. My lowly TS-400 can be told to change the spindle speed ...
