Hi, I am far from an expert, but will throw in some ideas anyway.
Step one is really to verify that you have power to all of the right places. So step one is to go through to every location where...
I am not sure if it is practical or not, but sometimes I wonder if a machine like that should be built to operate close to the floor vs at table height.
Now the table has been moved up higher on the legs to very close to the normal operating height.
Some of the leg frame work / cross members are in place, but I need to find / buy some more...
Now the frame is flipped over and more gussets are added.
I had to work with what was there and tack on some more supports for legs.
The legs are some second hand 1530 that I purchased from a...
I added some gussets to the 1530 framework to improve squareness and rigidity.
These double gussets are from parco.
In this photo, the machine is in the original side "up" so the short legs are...
Your build is looking really good.
Similar to you, we have had something go through the house, but it tests negative to everything so I guess it is just in our imagination.
Just throwing out the general idea that RF noise is not completely easy to eliminate. Make sure that all of your system is tied together to a good ground using braided cable vs solid wires.
In...
Just adding a link to the g code section of the forum for easy access.

Very nice.
Thank you for the reply and info - this particular one seems to be built in Poland but i am not sure.
Anyway, the actual use plan is a bit odd for most people. I am converting a non working cnc...
I am not sure if it would work for you or not, but the DIY router that I am rebuilding came with mach III.
For various reasons I purchased planet cnc hardware and software, plus the gecko stepper...
Continuing to accumulate parts and assemble / take things apart.
Slowly making progress. Sometimes...
It is not clear if any of these mini lathe spindle heads have tapered roller bearings in them or are just simple bearings.
Do the ones with tapered roller bearings usually call it out?
I managed to get it apart.
Some parts required persuasion with a wood block and hammer.
As far as if I ever need a replacement, it looks like Taig is an option.
...
Thanks for the resource list.
I just purchased some items from parco. They have larger items that I didn't find anywhere else.
Very happy with the parts.
I have also purchased a few related...
I am attempting to remove this head from the base and not having much luck.
I have most of the bed apart and mechanism but not the round hollow pipe like part (sorry for not knowing the correct...
Hi, I have the remnants of a small mini lathe.
The base casting has a "made in Poland" cast into it and a symbol mark that I cannot read.
It was given to me years ago and didn't really work...
Hi - how is your project going?
Thanks JonnyFive - that is very impressive work.
I am looking for a similar motor mount setup.
The ones that I am finding on line are only 3mm for a nema 23 motor.
Are you fabricating those or have a supplier?
Thanks
Harry
I completely agree that a higher voltage will give better results.
What I was looking at is the motor controller in your diagram. I am not sure that I am reading it correctly but it looks like it...
Your machine looks really strong and straight. Very impressive.
Reading the diagram, it looks like the controller is a 24 volt setup.
So yes, I believe that you take ( 24 volt ) x (peak...
Thank you. That is what it looks like to me as well.
I did find some size 23 stepper motor mounts on line after I made the post. They look pretty flimsy but perhaps will be good enough to keep...
For building my own stepper motor mount, I now have some 1/4 inch thick 8020 pre drilled plate that matches the 1515. You can see it in the prior post leaning against the back.
The hole spacing...

A few examples of the 15 series parts for bracing things up a bit.
My youngest son is being roped into getting the control stuff running after a long break.
He had demonstrated that at least one axis of the controller worked a few years ago using the controller...
Some more mechanical parts arrived yesterday - so that is always fun.
Various gusset connectors, 45s and plates for 15 series from Parco inc in Indiana.
They carry some items that are not so...
You are right - what you said makes perfect sense and solves a lot of issues.
Looks like success to me.
