I need to upgrade my old tabletop CNC, the old PC died… It came with MACH3 and I have been looking to upgrade the operation but keep the basic machine. My question is, will there be a compatibility issue wiring a superlongboard to this old machine’s motors? All I know is each motor has 4 wires. The…

So, as far as open or closed loop. I misspoke by stating the motors were closed loop. They are open loop. The same type as on the longmill. My mistake…I have already placed my order for the SLB along with the power adapter. I don’t know when the SLB will ship but, I have asked for the adapter to be …

@BrunRM Welcome to the group, Richard. Since you specifically mentioned using a SuperLongBoard, I have moved your question to the SLB category.

@BrunRM Others will be able to address the mechanical side of the conversion. However, the SLB will not work with Mach 3.

Yes, I understand. I intend to use gsender or ugs or similar. Thanks.

SLB requires a 24V 10A power supply. So you may need a larger 24V supply

Yes. If I purchase the SLB (I believe I will) I will also get the new power supply from Sienci … I think it would just make sense.

@BrunRM you might need to wait until the alternate version of the SLB is released that we’re working on for the AltMill if the steppers are closed loop since the current SLB has its own on-board drivers that only will work for open-loop steppers. That being said, do you know if your closed loop moto…

Ok glad to hear Richard! Good luck on the conversion, I hope it works out

Thanks Chris. I’m thinking it will just be X Y and Z running on the board. The spindle was running on a 48V power supply so I will keep it there. The motors were on a 24V power supply so I plan to just move those over to the SLB for now and power the spindle manually (if that makes any sense).
