Very Exciting Boring Machine Conversion
Hi all,
I picked up a 1999 Masterwood Speedy 207 a while back with only 6 hours on it. Previous owner had bought it, and never figured out how to use it. I fired it up before the tear down and it ran perfectly. It’s a VERY solid machine, altogether weighs about 3/4 ton. Ball screw on X/Y. Envelope is about 32” x 60” x 3”.
It was built to be a CNC boring machine for use in cabinet manufacturing. The table is a vacuum pod-and-rail system for holding parts. The original machine head had no router spindle, only a boring block with a grooving saw and a horizontal boring spindle. No Z-axis other than a pneumatic actuator that hit a manually adjusted stop.
The control was manually programmed by the operator but could not accept g-code from external CAM software. I gutted all electronics from the machine except for the power supply and brushed DC servos and encoders.
I’ll try to compile as much info here as possible, please let me know what is missing. I’ll be adding more over the next few days, CNC12 report to follow shortly.
Drives: Machdrive BRC on X/Y, Clearpath SDSK planned for Z
Servo X/Y: Brushed DC (see photo)
Encoders: Hohner PRO1310/500 located on ball screw.
The current status of the build is that I have the X servo connected, trying to get motion. I can jog the X axis at the Acorn but not seeing any step/direction lights on the drive. Also the drive is not indicating input of A/B signal from encoder with manual turning of the servo.

Re: Very Exciting Boring Machine Conversion
cool. look like a nice score.. i'd go with new axis motors on all three axes for sure.

Re: Very Exciting Boring Machine Conversion
That was my first inclination, but I couldn’t find anything with a shaft OD that matched up with the drive sprocket. I figured I already had motors that were engineered to fit the machine, so I opened the electronic can of worms instead of the mechanical one...

Re: Very Exciting Boring Machine Conversion
Now going through the CNC12 config wizard. What drive type do you recommend for Machdrives? "Other"? I'm not getting any step/dir signal to the drive, none seen on the oscilloscope.

Re: Very Exciting Boring Machine Conversion
Provide a link to the manual for the drives. You are sure they take step and direction?

Re: Very Exciting Boring Machine Conversion
Here is the manual for the Machdrives.
https://www.machdrives.com/pdf/BRB%20BR ... pdf#page16
Connection diagram:
I’m using the PS that came with the Acorn for 0V and 5V on both Acorn and drives. The only terminal that isn’t connected on the drive is the ERR.

Re: Very Exciting Boring Machine Conversion
I believe you need to use the DB25 on Acorn. Get a DB25 male breakout from Amazon.

Re: Very Exciting Boring Machine Conversion
If you are currently, trying to use the Acorn headers, you can try and go into the Advanced tab and invert step, dir, enable and see if that works....

OK. What is the difference between the DB25 and the headers?martyscncgarage wrote: ↑Thu Nov 14, 2019 3:57 pm I believe you need to use the DB25 on Acorn. Get a DB25 male breakout from Amazon.
I’ll try inverting the signals first. The ENABLE signal is currently being received by the drive. So that’s a start!

DB25 is similar to a parallel port. 5vdc logic already there for Step Dirdustboy wrote: ↑Thu Nov 14, 2019 4:21 pmOK.
