this was my final conversion using the dlc 32 and 2.4" screen, a 110 3 phase brushless spindle on a custom adapter plate and i swapped for a stepper motor with 4400 g-cm holding power for the additional weight and am running 8825 drivers on 32 step
so far other then a couple glitches this setup is liking the millmage platform, I normally use opencnc but am really liking the millmage interface
I can’t believe how quiet all of it is…
I am trying to get the spindle vfd hooked up through the ttl or pm I do have analog adapters and such but am brain farting on the settings and wire hookup
Please help me get variable speed hooked up LOL
Are you using the pwm inputs to your motor controller?
Do you have the directional input set to the proper direction?
no it is supposed to have ttl and m trying to figure it out
The DLC32 does have a ttl compatible pwm output, it’s up on the laser connector… the S pin is the ttl output.
Here is the output schematic of the dlc32. The top right connector and produces a ttl voltage pwm at pin 3 of J18.
Make sense?
actually not sure where each wire would land on the vfd…
Looking really good, and promising, but I think you need a better connection diagram for the VFD.
yeah so do I… I use to wire up a ton of vfd’s and I have to say that is one of the worst quality schematics I have seen and the retailer is absolutely useless
not to mention these boards already have a problem on the usb side for failure…
i have the ttl going to the pmw and testing it i get 5vdc from the ttl to ground on the board when i use the variable speed command. So I know I am able to send a 5vdc signal from the board to the VFD. I have P0 set to 1 external pmw, P2 set to 0 0-5v, and P3 set to 1 High level output DC5V.
I have not hooked the ground upto the GND from the board to the vfd as im not sure where to hook it to, I would guess it would goto control signal common ground but not sure…
If you don’t have a common signal ground (such as ground), all of your measurements you used with reference to ground mean nothing.
This shouldn’t be rocket science. Get a better wiring diagram so you can see what you need to connect to what.
What boards and what do you mean?
these dlc32 boards have weak usbch340 chips and they fail quite a bit if they sense any little short or a strong wind it seems
i would love to get a better schematic but the retailer can’t provide it and allegedly the factory engineers can’t provide a better one… i can test it using a separate source and ground so i don’t put any strain on the mks and i’ll try that for now and if that works then i’ll go from there…
I’ve posted the partial schematics of the DLC32 and the whole schematic is available via github.
I’ve used the 
out of my DLC32 with zero USB issues.
If you’re referring to the Chinese pwm to dc motor control voltage box, they won’t tell you much about it’s internals, but you should be able to read how to wire it up from an external users view, if not I’d find something else. If you have to guess on wiring, then you have the wrong product/manufacturer.
You can get pwm to variable dc voltage boards all over the Internet, but you still need to know how to wire to your control box. Is it not marked on the device?
Can you provide a link to the manufacturers site for this?
i would love to provide one but all i have found are retailers and the same manual i have. if i am correct if I set the aparamaters down to low so it is looking for 5volt then just a variable 5 volt source and to the pmw and a ground from that same source should be all that it needs
yeah the way i read that is the 5 volt from the ttl goes to the pmw and the negative from the same plug goes to the ground to the control signal, do you see the same thing?
i would believe through my understanding that when you start getting signal through that at the 0-5 volt range it would start the spindle up at the speed in the direction you set the parameter in the unit at
with the following parameters set at
P0=1 for external pmw
P1=1 cw/ccw start
P2=0 0-5V
P3=1 high level 5v output
P4= direction wanted stareted
