Just an update, spoke to DMM via email, they recommended their 400w motors and dyn2 drivers.

Recieved all the pieces and cables, bench tested and installed. Just got it wrapped up last night. Got...

Fantastic. I'll work towards pricing out that route. I believe it would make the machine more suitable long term as well. I own a small custom machining shop, would be nice to have a dependable...

Thanks for the info Craig. I've actually been looking at the dmm servos as I live in Canada. Trying ti decide between their dyn2 or dyn4 units. Then I can decide just how big I need. My current...

Awesome! I'll look into that route. Appreciate it!

The machine never came with a controller and I retrofitted the machine with a digital dream ddcsv3.1. If the ac servo driver accepts a step and dir signal it should work no issues.

Now for the...

Oh wow. This is somewhat disappointing but good to know. I'll start looking into what can be done to convert it to servo drives. My controller doesn't have a spot for position feedback, just a...

Thank you very much. I'll definitely take that advice. The ball screw is half the speed of the motor, with a 2.5mm pitch.

From reading the pacific scientific literature the voltage for these...

Another thing to add. Doing research I realized that the specs for this machine were using the original dc servo axis drives.

I may be over spinning the axis motors when utilizing rapid motion....

Confirming I have 51.5V at the stepper driver, even while Y axis is homing. I'm unable to verify at a higher speed. Could that be a potential issue ?

Edited: had someone hold the y axis button,...

Based on this diagram, the motor is wired in bipolar parallel. I'll verify the drive voltage when I can tonight.

I really appreciate the quick responses. This machine is a work horse for me when I...

Thanks for the description. Maybe my issue is this axis is wired differently, hence the issue on one axis.

I'll dig around and verify a few things you all have suggested, driver voltage and the...

I've attached some photos.

I'll check voltage at the driver tonight when I head out to the shop.

Alright. Going to try my best to answer. It's a dyna myte 1007 10 inches x 7 inches travel.

I'm unsure how to find the rest of that info. They're 8 wire and it's wired in pairs of 2 tied...

Hello, I've been having an issue with my converted cnc milling machine that seems to be progressively getting worse. It seems to be losing steps of sorts on the X axis only.

The machine uses...

Thanks for the insight. I purchased a Chinese ddcsv3.1 to use as a standalone controller. It should also provide a means to control my spindle using a 0-10v signal.

I'll post some updates when I...

Hello everyone, I've been slowly working my way through my new to me milling machine. Its a Dyna Myte 1007 Converted to mach 3.

The machine uses a pmdx-122 to connect to mach3. I have managed to...

A few more images.

I just picked up a Dyna Myte 1007 milling machine. From the quick look over i did, it doesn't seem to have (or ever had) a built in display or controller. However inside the electrical enclosure it...
