Closed Loop Motor Setup
-
@alankilian ok understood thank you for all your help. Do you mind if I came cross a problem or if I have a question regarding motor programming I can reach back to you
-
@moe-adams9093 For sure. I'll send you my email address in a message.
-
@alankilian @moe-adams9093 Just Read all your messages since my Last message.
@moe-adams9093 That is exactly what i have been seeing, Its a continuous Layer shift through the layers. Some Worse then others. Im hoping We can Resolve this. But Its not the end of the world. Just the end of $200.
@alankilian I sort of agree with you about Closed Loop Not Really adding any benefit, To me, Its more of a "Lets do everything we can to prevent a layer shift" (Although I can see as the motor increases the Torque, It just pops the print off the bed)
Im still in it for the rest of the People. This is a popular Motor for people to have. Getting it working should help quite a few.

@3dpmicro That's what I Heard! But Its really Expensive. Im Buying PEEK Pellets for Roughly $45/Kg, Then The Power costs to produce the Filament when I get everything Set up.
Ill give it a shot when My Voron Gets Built. I Got CNC Aluminum Parts for the Voron Gantry So it can Handle the High Temperatures
PEKK is Something like $800/Kg I think PEEK is Slightly Cheaper Around $700/Kg. Only went with PEEK Because For Some Reason, Its $45/Kg for Pellets.
Know a Place to get Reasonably Price PEKK Pellets?
-
I run these same motors on my printers, took me a long time to get them working correctly but I think I am close. I was getting inconsistent layer shifting until I started going crazy with the T parameters.
-
@toastinator I was generally of the opinion that printing with something cheap, like solid gold, was easier than going for high-end PEKK and PEEK.
-
@toastinator he's only showing pekk/cf pellets
https://www.3dxtech.com/products/pellets-colorants/ but you could inquire about unmodified Pekk although pekk/cf is my favorite by far. Second in modulus only to peek/Cf but is easy (relative) to print, makes good looking parts and can use all the way up to 260c.

@3dpmicro Looks Really Good, Do you use a ruby Nozzle for that? Or Just a Plain Hardened Steel Nozzle? Thanks for the advice, Ill look into it
@mendenmh You could be Right, But I love a challange!
@taylo708 Are you Using a Duet 3 With Duet 3 Expansion 1XD Boards for these Motors? I went Crazy on the T Parameters with no Luck
-
@toastinator Yes I am using Duet 3 with 3 expansion boards. I run them on x,y and z axis.

Slice engineering nozzle. Guaranteed not to wear out.....we'll see
Forgot to mention you want PEKK "C" not "A" -
@taylo708 Ok, Im only Using on X/Y Axis. My Z Axis has 3 Motors. Im Almost done Printing the Parts for my Voron 2.4 Build. When I get the Motors back, I Should be totally done and can Start Digging into why these are doing what they are doing.
@3DPMicro Gotcha Thanks, Have been Looking at the Slice Magnum Setup for a while

@toastinator I'm not mailing you the motors and logic analyzer today because:

Thank you to everyone who is working on this. I just received the JSS integrated steppers yesterday. Driving them from the external driver headers on a Duet 2 Maestro. Also will be used for CoreXY, in my case an FT6 conversion. That print quality example is concerning but I guess now that I have the motors I'll give them a try in the printer and see how it works for me. Running RRF 2.05, all I had to do was flip the enable polarity and the motor worked (though poorly for long move commands). Changed timings to 2:2:2:2 and now it works smoothly.
-
@taylo708 Is there any chance you could dm your config.g file and also wiring diagram for these motors on duet 3 and 1xd boards?
im rebuilding a printer that contains these motors on x and y and then z has an mks tb6600 driver.
im probably missing something simple but new to the whole duet ecosystem after playing around with marlin for so long.Cheers

@Toastinator Hello, I tried to install ESS ProTuner software from that link but i think it's deleted from OneDrive. Could you tell me where can I find this software because I checked everywhere but i
