Closed Loop Motor Setup
-
@alankilian I contacted jss motors last night and they just sent me the zipfile for the software. Did you use any RS232 breakout board to connect via USB and man there’s lots of settings in here to play with. So let’s say if I change anything what will I set the dip switch I’m assuming all set to default because it’s going to over write the default settings maybe?. Thank you
-
@moe-adams9093 This motor uses "real" RS232 signal levels, so you do need a USB-to RS232 adapter. Most any will work.
You use the DIP switches to set some of the settings and the software to set others. So the DIP switch settings are still important.

While Also Experimenting with a Filastruder to Make my Own PEEK and PEI Filament. Im Buried in Projects!
Try PEKK instead of PEEK. Better than PEEK in some respects and waaaay easier to print
-
@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
