Thanks Martin, turned out to be a dodgy wire! would never have thought to check that.

Does anyone know if it would be safe to cut the Z axis proximity sensor and splice it into the X axis side? Want to test if it is the X axis sensor thats causing the issue.

Its a baldor control board & VR turning 1.51

Hi All, I suspect I have a faulty x axis proximity sensor on my mirac PC. Homing the Z axis works as expected. But when homing the x axis, it either moves up untill it hits the end of its travel or mvoes down until it hits the end of its travel. I am assuming this is becuase it has not received the ...

Thanks for that top tip david, that was enough to get it talking again! I never would have thought of trying that!
I guess im still on borrowed time with that board though. But now I have a chance to put some cash aside for it!

Thanks for your reply, that's very helpful! Just wanted to rule out the cheapest fault first! as the cable is fairly vunerable in my workshop. I wouldnt have thought the spindle was over loaded as I only cut plastic around 16mm dia, and not usually more than 0.5 depth of cut becauase of the long sti...

Hello, me again! Needing some help trouble shooting some connections issues on my MIRAC PC. Halfway through the day, the machine began slowing down, as in, the time between each movement got longer and longer. I decided to wait it out untill the programme had finished before I then restarted the sys...

alternatively..... anyone want to buy a tutor keypad?

Does anyone have the time to give a step by step guide on how to connect up a desktop tutor keypad? I have read all that I can find on it but no success. I have two rs232 com ports on my pc, im using a 25pin to 9 pin cable (again I have 2 of those so I dont think its the cable). Both cables work to ...

Software is VR turning v1.49.0.0
Sorry, I'm new to vr turning! you'll have to point me in the direction of the control panel...
Do you mean machine parameters? There's a check box for high speed cutting under "machine capability"?

Thanks

My mirac pc pauses between each block of code. For example, if the program was to read: N010 G01 X15 Z0 N015 G01 X15 Z-5 N020 G01 X15 Z-20 Then the feed would pause for a considerable time at Z-5 leaving a gouge in the workpiece as it chatters. ( I know you would not normally use such a code as abov...

I’d let it go for £250

Union: 28.40 dia x 35.30 to the register.
Brass fittings are 19.20mm
The jaws don't wiggle as they're under tension.
The jaw can still be repositioned as you would normally.
I'm in Scotland. International fedex would be around £75.

So a little research has told me that Deublin is the company that made pneumatic coupling on the back of the chuck. It is actually a leader chuck systems brand air chuck - although their website is pretty terrible as all the technical info is missing so I can't be sure what model it is. At some poin...

I have now sourced a manual chuck, so yes! I would be open to offers.
I have some more info on the chuck too, I will post later tomorrow.

I have recently pruchased a Mirac PC with pneumatic chuck fitted, however for my needs a manual chuck would be much easier. Deublin Ltd is stamped on the back of the chuck. 4" 3 jaw chuck, 4000 rpm max, 6 Bar max pressure. I have the back plate and all the solenoids etc to make this work. chuck appe...
