Upgrade CNC with Closed Loop Steppers?

- After 6 months of use, was this update worth it? In Sept. 2022, I upgraded my CNC router with closed loop stepper motors and drives. This video answers the question "Was it worth it".

Very nice explanation, I have realized the price of closed loop systems is way down now, and so will be swapping mine out as well.
Hi ServiceProcess,
Thank you for the kind words! Yes, it is much more affordable today and it certainly is advantageous to have a closed loop system!
Cheers!

great carvings, fine machine, could do faces or couples, the burn effect might even be a feature if it can be controlled.
Hi Ben,
Thanks! The burn "effect" is very damaging to the tools so it would not be an ideal thing to do.
Cheers!

Hello can u explain how to invert the direction of the motor so that 2 motors can be on the same axis using NEMA 34 and hsb860h driver. I mean detail wiring
Hi olufemisotunde3868,
I would need a lot more information about your system to create a custom schematic on how to wire up your drives and motors and that would require more time than I have available. However, assuming the drive is a step and direction drive, the only thing you need to do is set the direction pin to low for one motor and high for the other motor and they will run opposite directions.
What you are probably trying to do is have one output from your control software (such as X axis outputs) drive TWO motors. That is not the best way to do dual motor drives on a single axis as it causes many problems. Your CNC (assuming CNC) software should allow you to set a "slave" axis that would provide that motor with its own Step and Direction signal data.
Hope that helps a bit.
Cheers!

Your software acknowledged the alarm where most do not. As in grbl and others so the alarm means nothing and doesn't do anything.
Hi LarryScott,
The Centroid software is on a MUCH HIGHER level that grbl, of course, the cost explains that too. I have used a lot of the very entry level CNC software, my favorite is MACH 3 (not the newer stuff) when Art was still in control of it. It was far from perfect but the price was right and, WOW it could do a lot for the money.
I am an Applications Engineer with a machine tool company (have been for nearly 40 years), so I am pretty spoiled in that I get to play with the big toys. Ultimately that is what led me away from the entry level stuff like MACH and grbl, they are fun but I don't have time nor patience anymore to tinker around trying to get those packages to perform the way I want them too. The Centroid Acorn was a stab in the dark, but it certainly has proven to be very robust and reliable - definitely in my "good purchase' column.
Cheers!

What board are you using ?
And which drivers ands motor ?
I assume by "board" you mean control. It is the Centroid Acorn. The drivers and motors are from Automation Technologies.
Chris
@@MakingStuffwithChrisDeHut how do you like the centroid acorn ? Would you still go with that controller if you had to do all over again ?
You can very much tell the difference in quality and performance between the Acorn and all other "hobbiest" level controls, hands down the Acorn is more reliable and robust. It may not be as "open" as MACH 3 was, but is sure is more capable.
Keep the ball screws!
Hi Jack,
Yeah, the older I get the more I realize I don't need things going faster!
Cheers!
