RRF M669 Kinematics Issue
-
RRF 3 issues
My printer (Duet 2 Wifi) has been sitting in my garage for 18 months while i moved back to the US. I've finally gotten around to getting it going again. I am issues with it dropping out, some HTTP error message. Thats not important right now. After a bunch of heartache stepping through firmware and DWC upgrades and switching to an extra Duet 2 Wifi that I had extra, I know sit at
RepRapFirmware for Duet 2 WiFi/Ethernet version 3.4.5 (2022-11-30 19:36:12) running on Duet WiFi 1.02 or later + DueX5v0.11
With DWC 3.4.5
I was previously at FW 2.02 and DWC 1.22
The issue is that my config file is from FW 2.02 that ran great is now offending and as it tries to execute config.g at startup it craps out the wifi. I started with a blank config file and then started adding line by line, until I found the offending line in the config
M669 X1:0:0:0 Y -1:1:0:1 Z 0:0:1:0 U 0:0:0:1 : set custom Kinematics
Now,I have an abnormal kinematics setup, Its sort of like a "double mark forge" setup. 2 Y axis motors and a motor for x and a motor for U axis, each with a giant belt in an H- shape.
Problem is I don't know how to make this line of the config file not crap out. Am I missing a newer parameter in RRF 3?
Update: I guess its a coreXYU by looking at samples on the internet. I have tried adding K1, then K5 and the same thing, wifi drops on power up.
-
@DougJones are there spaces after Y, Z and U? Though the firmware isn’t usually that picky. Try removing them if so. M699 should work, so there may be something else in your config that’s causing problems. Perhaps post the whole config.g?

Nope, No luck. The config file still hangs. I removed the spaces, then tried to add the K5 parameter for CoreXYU, still no luck.

Can you post the full config.g file along with the results of M122 and M98 P"config.g" please?

Have you tried with just M669 K5?
-
@Phaedrux
That seems to have loaded the config file without issue. But there is no way that the kinematics are setup correctly, right?My mistake, I did not apply the config file. When I did, the WIFI dropped and the DUet locked up again.
for reference it is not a corexyu
it is exactly this:
-
That's quite strange. Can you try something more pedestrian like M669 K1 for a plain corexy? Don't move anything obviously, I just want to know if it causes the same problem.
-
Yes, same problem is confirmed.
I feel like I've tried every possible combination. Anytime the M669 command is in the config file, the unit seems to lockup with no wifi.
I have to pull the SD card, insert it into the laptop. Comment out that one line and DWC loads and I get a blue light on the wifi module.
If i go into the config file edit it to uncomment the M669 line. The blue light on the wifi module drops and I cannot access the duet.
-
@DougJones I confirm that there is a bug that is causing the Duet to reset. I am investigating it.
-
@DougJones this problem is that on this line:
M669 K5 X1:0:0:0 Y-1:1:0:1 Z0:0:1:0 U0:0:0:1 : set custom Kinematics
you have used ':' instead of ';' to introduce the comment. A bug in the RRF handling of some M669 errors is causing the Duet to reset instead of displaying an error message. I will fix the error handling in RRF 3.5 and 3.4.6.

Great. I will try this later today. My eyes must be getting bad....I've stared at that one line for several hours and not noticed.

Okay, great that fixed the issue with the config file. Now, onto the second problem.
The Duet keeps disconnecting about once per minute. It shows from M122 as
WiFi Vcc 3.40, reset reason Turned on by main processorMy wifi signal is very good as I installed an access point directly next to the machine. Its the same access point that ran the machine previously in the old house. Its a TP-Link Deco, so I don't have a lot of options for channels and whatnot. I've been through all the other posts about this issue and have yet to find a solution.
WiFi signal strength -34dBm, mode 802.11n, reconnections 0, sleep mode modemIt seems pretty consistant every minute or two the DWC disconnects

@DougJones Can you verify that your DWC version is also 3.4.5?
You can also try reflashing everything by uploading the full release zip file to the system tab in DWC.
https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.5/Duet2and3Firmware-3.4.5.zip

@Phaedrux
Yes. DWC is 3.4.5 -
Yes, everything is re-flashed now and same response
update: I just spent 2 hours getting another AP setup with its own SSID and trying to connect the Duet to that, only to realize that its a 5GHz only AP. I cannot seem to catch a break here. I liked this idea of having a "3D printer only" wireless network to keep it from "hopping" AP nodes on my mesh network. And I has this really nice TP-Link Pharos AP that allowed me complete control to select channels/frequences, etc.
Off to FB marketplace to see if I can get a cheap AP/Router to test with.
-
For what it's worth I have a very old 2.4ghz router that provides a network for the printers and it's been going strong for years. There have been a few other reports of mesh routers not playing nice.
@DougJones said in RRF M669 Kinematics Issue:
only to realize that its a 5GHz only AP
I didn't realize there was such a thing. I thought they were all combo units.
-
@DougJones it's probably not relevant to this issue, but running RRF 3.5beta2 with your config.g file I see these startup errors reported:
Error in start-up file macro line 32: Driver 7 does not support x4 microstepping with interpolation Driver 8 does not support x4 microstepping with interpolation Driver 9 does not support x4 microstepping with interpolationThese relate to the M350 line. You could avoid them by using two separate M350 lines, one for Z (with I0) and one for the other axes. But is there a reason why you are running Z with just x4 microstepping instead of the usual x16 ?
This board is also running WiFi firmware 1.27 and my WiFi is also a TPLink Deco mesh. The connection is stable. An app on my smartphone indicates that the mesh system is using channel 4.

Okay, I have a new AP installed in the garage with the printer. Its a TP-Link Pharos with b/g/n @ 2.4 GHz. The printer now has its own SSID and its isolated from the DECO system. I'm at about 30 minutes with no disconnections. I am running channel 6 with WPA2-psk with AES and 0 db of antenna boost. This Pharos unit lets me control everything through its web interface.
For reference: I had a TP-Link DECO M5 system for years and it ran great. When we bought the new house a couple of months ago, I upgrade to the Newest, fastest DECOs that support wifi 6E (its an XE 75). The system works great, but this isn't the first device on 2.4Ghz that I have found a little flaky.

I'm not sure why i am not using x16. I feel like there was a reason for this years ago when Initially set this up. I think that I might have been worried about the weight of the z-axis. At the time, I had 2 ballscrews connecting an aluminum plate x axis. I think I might have been concerned about the drop off in holding torque for x16 microstepping (maybe wrongly, but I think that was the reason).
Now my setup is 4 independent z-axis motors each controlling a ballscrew to do mesh leveling and remove some of the twist in the heated bed. That system works great.
If its okay, I might leave this alone for now, but I can test moving to x16 once I have everything moving again.
M350 X16 Y16 Z4 U16 E16:16 I1 ; configure microstepping with interpolationI think you are suggesting that I should do this:
M350 X16 Y16 U16 E16:16 I1 ; configure microstepping with interpolation M350 Z4 I0Update: Well.....she is up and printing again..... Thanks for all the help. WIFI is infinitely more stable now. I'll do a few test prints, dial everything in real good and then I'll have a look at the z axis x16 settings
