Hi,

I'm toying with converting my Triac PC to a MACH 3 system and would like to take the opportunity to improve performance as well.

Can anybody tell me the specs of the existing steppers please?..... the X axis is easy to see but the other 2 are a little buried!.... after peering in the top ...

These questions have probably been asked a million times here but search didn't seem to bring it up.

Is there such a thing as a service/workshop repair manual and parts books for a Triac PC Mill?

I'm thinking of stripping my unit down, I definitley need to replace the spindle bearings as there ...

Hi,

Don't suppose you have the analogue speed control card for a TRIAC PC, please see my other post:

Thanks

It's working again! :D but only with manual control :cry:

I fitted the new sprint board copying the dip switch and pot settings from the original and away it went.

After a satisfying myself it was all fine I decided to take off my 10k pot and try the analogue connection again.... as soon as I ...

Here is a picture of the card, it may help identification.

All this help is terrific on here..... Thanks

Just to let you know I spoke to Sprint, really helpful guy (Jim) suggested I check between 1 & 4 for 10v, there wasn't anything (about -.3v) so we have concluded the spindle drive is indeed faulty. I have ordered a replacement (nice to know they still ...

Thank you for your help so far, I will try the seperate pot test tonight as I don't have any kind of manual pot on the machine.

Are both of my suspect cards impossible to source/repair now?..... if you have any or know a repair shop I could make contact today and get prices.

Is the analogue ...

Well a little inconclusive I think.

Analogue input runs from 3v - 4.2v when I run the onscreen pot in VR milling from 250 -4000

Hardly any change in output DC voltage, runs between 18-20v when I move the onscreen pot from 250-4000

AC Input is 240v

There is something else I noticed with the ...

Thanks Guys!!... When I was looking for a machine I decided a while back it had to be a Denford simply because of the strength of this Forum and you haven't let me down.

I will be striaght onto this tonight and let you know results in the morning.

I tried to look at those last night, removed the cap, then removed a retaining ring but could not see how to get the brushes out.... is there a special tool or do I just grab the brass bit with a pair of tweezers or something and pull?

Do the voltage at the terminals seem correct?

Thanks

Paul

Hi everyone...

I recently bought a Triac PC (modified for USB and VR Milling CNC) from Ebay, my first ever CNC mill that I bought to learn a bit about. I have only had it a couple of days and it has seemingly broke. To be fair it is an old machine the guy selling it did say he noticed the spindle ...

Hi, I have just picked myself up a Triac PC on Ebay that has been converted to a USB interface and came with the latest VRMilling CNC program.

I don't know the first thing about CNC machines but I have bought this to do a bit of learning/playing.

I want to be able to mill 3D items from Solidworks ...
