Try using thermal transfer pads.

Here is a screenshot of my Lathe controller cabinet schematic. This is the AC wiring only. Others may do it differently but this works for me without getting too technical. You can use it as a...
I was going to send you a photo of the enclosure that I use but then started looking at the size of your servo drives. Then I decided that it wouldn't be useful to compare a random case size to what...
This issue is a prime example of the problem of making Safety "Priority One".
Mike Rowe, of Dirty Jobs fame, has a saying that addresses this very issue "Safety Third". You can read about it...
BTW, I am just now looking, closely, at your schematic. On the contactor, don't you want to turn it on and off by using one of the outputs from the MB3? Take a look at page 21 of the MB3 manual for...
Here is a quick resource for calculating the diode value. Your power contactor may have a recommended value so start there.
BTW, I have always heard of it referred to as a Flyback Diode. Anyhow...
My $0.02 for what it is worth.
Why are you not wiring the stepper enable signals. There is plenty of I/O left over to hook those up. When you press enable on the computer it will lock the...
I made a depth stop for the spindle. It screws into the spider nut and is secured with the brass knobs.

With regard to ExpressPCB.
I have always found that a good starting point is to see what someone else has done and adapt it from there to meet one's own needs. If you have any interest I will be...
I second using ExpressPCB. The cost is not all that much for a small board and you get very professional results. Their new software can export a gerber file for use in other applications. Also...
I think you would be best off starting with a manual lathe frame. I did a conversion of a PM1228, probably bigger than you would need.
Maybe start with a Harbor Freight Mini Lathe.
...
You didn't say how many steps/revolution the encoders are or what the number of micro-steps the steppers are using.
I could see a situation where an encoder could report multiple steps where the...
Show us a screen capture of your M4 system. Both the mill and lathe screens have a RPM DRO right there. Are you not seeing the indicator or is it showing incorrect data?
If you are running cable, Run 2 circuits. One 12AWG for a 20 Amp 120VAC and one 10AWG for a 240VAC 30 Amp circuit. You could run the PC and electronics off 120VAC and the VFD off the 240VAC.
Just a quick note to demonstrate why one might be better than the other.
It is always a good idea to configure your circuit such that if the cable breaks or becomes disconnected the limit switch...
I wanted to turn threads on a gun barrel and needed a spider nut to keep the barrel centered in the spindle. What I made is a new nut for the spindle. Here it is. Some brass screws will finish it...
Gosh, you have bitten off a lot. New to 3D printing and new build it yourself machine.
In my experience:
You should print out a Benchy and post up some high resolution photos of the results. ...
Agreed. Honesty. You don't have to give too many details, just the basics. It is the responsibility for a manager/owner of the business to make sure that the loss of one person is not a detriment...
Mach 4 runs on windows which is not a synchronous OS. Windows can't produce the precise time based pulses needed for smooth motion. This is why you need a separate controller to take the movement...
I made another modification to the lathe. I replaced the discrete interface cards with a universal BOB for the ESS controller. Here is the thread for the new BOB. ...
Since you are talking Mach 4 then you could setup your system with a smart controller like an Ethernet Smooth Stepper. The ESS handles all the motion calculations and Mach just sends it commands. ...

It's a Jeep signature look to have 7 vertical slots for the radiator grill. While your pendant looks really nice a jeeper would know.
Just sayin.
...
It's not really a Jeep if there isn't 7 slots.
For what you are talking about doing the amount of work and cost will probably be greater than a new/used mill and it may also turn out to be a bigger problem. There are many aspects of the G0704...
Do you have the acceleration values setup properly?
I am pretty sure the head should reach max velocity during the lead in and lead out process. Fusion will always try to keep the chip loading...
You might think about using a different alloy. 3105 has poor machinability qualities. Also, when machining aluminum plate on a router, you need to be careful about your speeds and feeds and ramp...
Final update on the BOB project. I finished the board, software and completed all the testing so not it goes into the lathe. Originally I built my lathe conversion using discrete boards for each...
This is a very good article to explain how pull-ups/down work.
One must also consider the beginning state of a circuit to determine if the signal should be pulled up or down. Look at a spindle...
I was never able to resolve the issue, except that putting the original controller back in got the RPM that I needed. I did contact Matt at Precision Mathew’s and he did not have any recommendations...
