Does anyone know if it is possible to replace the S5P stepper motors with the HDM’s larger higher voltage motors? Now that we are running a larger 2.2kw spindle and coolant on parts, the weak link has become the stepper motors not being able to push the feeds further in roughing operations.
You would also need to upgrade the 24V power supply and the electronics which is not easy to do. I am pretty sure the inductive end stops and the front panel that the BitSetter and BitZero plug into are all rated for 24V. As such you would need to either replace those or get a control board that supports running one voltage for the stepper motors and a different voltage for the probes.
@CthulhuLabs is right, there’s some components that run at whatever native voltage the controller runs at and some won’t take 36V well. Some are on the controller PCB itself, so going to 36V is a no-go.
You could get longer NEMA23 stepper motors that are rated for more power, and you will get a little more torque out of it, but you’ll quickly run into the current limit of the stepper drivers.
I think the TLDR is you could squeeze maybe 20-30% more torque out of the system, but anything beyond that would require you to violently rip off the warranty band-aid and substitute in your own controller.

He’s already voided the warranty by using a spindle not officially tested for the machine so go for it.

We’ve seen other customers use it, but plugging in other, untested electronics does void the warranty: Carbide 3D Machine Warranty )
Thank you for the feedback everyone. This is kind of what I feared. In the long run, I may go with a Masso conversion and make this an ATC machine but only time will tell. I am achieving some great MRR with this setup though! I cut run times down to a 1/4 of what they were with the old Makita Router

Which 2.2kW spindle did you use? What do you normally cut? Just curious because I’m going to upgrade likely to the 1.2kW VFD but mulling my options.
I went with the PwnCNC 2.2kw metalworking spindle and their VFD kit. It’s working great and I pretty much only run 6061 aluminum parts at this point.
