Re: Help needed with PM-940m CNC VS conversion to the Acorn Controller
thanks for the link to those schematics.. had an interesting time registering to the hobby machinist but was successful. could not view the schematic it said I did not have permission.. So you can't see the posts on page 2? I don't think there is anything special about that post. Also, PZ is correc...

Re: Help needed with PM-940m CNC VS conversion to the Acorn Controller
NcKarl, Do you have a PM-940 that you are experiencing the issue with? I had to wire my relays back in to make it work. RickwJenn was able to eliminate the relays by following Jake's diagram. Please see the following post: https://www.hobby-machinist.com/threads/pm-940m-cnc-vs-motion-controller-conv...

Re: Spindle Encoder
In this scenario, i can go with either. I'm going to put a timing pulley on it so if there is a good shafted encoder i can go that direction, and if there is a good hollow shaft encoder i can adapt that too. The big thing to me now is if it will work with the higher RPM and if it will work well with...

Re: Spindle Encoder
I didn't talk to the folks at PM, but the guy that setup the bearing carrier did something similar to his. So, i'll see where it goes. The one thing that I need to do is be sure that i'm putting a decent encoder in place because i'm going to have to mount it in the head of the spindle once I take th...

Re: Spindle Encoder
Thanks for the replies guys. I have the Variable speed version and not the 6 speed mill. I had a guy modify an extra bearing carrier that I had and he told me to try it with the bearings that are in there that they were good to around 6500 RPM. I'm also changing the motor and going to a belt drive. ...

Re: Spindle Encoder
Thanks Dave for the input. The one you bought from Centroid, is it the same one that they have listed in the accessory section of the AllInOne page? Or did you call in and have them suggest one?
Thanks again,
Doug

Spindle Encoder
Hi All, I'm looking to add a spindle encoder to my PM-940 machine with the Acorn. I'm figuring on using 2 timing pulleys/belt in this setup attached to the spindle. I'd like to get one that's decent, but isn't going to break the bank. My spindle will probably run between 6 to 7000 RPM. Can anyone re...

Re: Passive Probe Issue
In Acorn I have Input 7 set to Probe Tripped NO and I have input 6 set to Probe Detect NO, but there is nothing connected to the input 6 terminal.
Attached is the Tormach doc for the probe. Pretty straight forward. Not much info.

Doug
