Duet xy moves inconistent after printing (Solved)
-
Edit: The z could not keep up with the moves of the x and y axis which caused the stutters. Increasing the accel and jerk on the z axis fixed this.
Hello,
My printer is having a strange behavior. When first booted, the printer moves smoothly. A few minutes after a print starts, it will start and stop when told to do long moves.
Here is my config file

Thank you. -
I notice you're using some very high microstepping values. This may be causing hiccups.
After you experience these stutters, can you please send M122 in the gcode console and copy and paste the results here?
Do you use mesh compensation? (G29)

I have a print that will finish in a few minutes so I will run the command after that.
I am running bed mesh leveling.

This is pretty long.
My wifi is a bit lousy at the moment but I'll fix that later.M122 === Diagnostics === RepRapFirmware for Duet 3 Mini 5+ version 3.4.5 (2022-11-30 19:41:16) running on Duet 3 Mini5plus WiFi (standalone mode) Board ID: F308N-B196U-D65J0-40KM8-LH03Z-ZZP2K Used output buffers: 3 of 40 (22 max) === RTOS === Static ram: 103652 Dynamic ram: 113092 of which 0 recycled Never used RAM 21272, free system stack 118 words Tasks: NETWORK(notifyWait,3901.0%,199) ACCEL(notifyWait,0.0%,346) HEAT(notifyWait,28.6%,324) Move(notifyWait,541.2%,265) CanReceiv(notifyWait,0.0%,942) CanSender(notifyWait,0.0%,336) CanClock(delaying,13.5%,341) TMC(notifyWait,634.3%,106) MAIN(running,3180.7%,417) IDLE(ready,42.1%,30) AIN(delaying,802.9%,263), total 9144.1% Owned mutexes: === Platform === Last reset 15:55:29 ago, cause: software Last software reset at 2022-12-13 22:39, reason: User, GCodes spinning, available RAM 20732, slot 1 Software reset code 0x0003 HFSR 0x00000000 CFSR 0x00000000 ICSR 0x00000000 BFAR 0xe000ed38 SP 0x00000000 Task MAIN Freestk 0 n/a Error status: 0x00 MCU revision 3, ADC conversions started 57329657, completed 57329657, timed out 0, errs 0 Step timer max interval 1490 MCU temperature: min 31.4, current 43.9, max 46.9 Supply voltage: min 12.8, current 13.0, max 13.4, under voltage events: 0, over voltage events: 0, power good: yes Heap OK, handles allocated/used 99/0, heap memory allocated/used/recyclable 2048/716/716, gc cycles 1 Events: 0 queued, 0 completed Driver 0: standstill, SG min 0, read errors 0, write errors 1, ifcnt 145, reads 2222, writes 29, timeouts 0, DMA errors 0, CC errors 0 Driver 1: standstill, SG min 0, read errors 0, write errors 1, ifcnt 39, reads 2242, writes 9, timeouts 0, DMA errors 0, CC errors 0 Driver 2: standstill, SG min 0, read errors 0, write errors 1, ifcnt 84, reads 2206, writes 45, timeouts 0, DMA errors 0, CC errors 0 Driver 3: standstill, SG min 0, read errors 0, write errors 1, ifcnt 74, reads 2206, writes 44, timeouts 0, DMA errors 0, CC errors 0 Driver 4: standstill, SG min 0, read errors 0, write errors 1, ifcnt 176, reads 2220, writes 31, timeouts 0, DMA errors 0, CC errors 0 Driver 5: not present Driver 6: not present Date/time: 2022-12-14 14:35:29 Cache data hit count 4294967295 Slowest loop: 212.10ms; fastest: 0.08ms === Storage === Free file entries: 8 SD card 0 detected, interface speed: 22.5MBytes/sec SD card longest read time 7.8ms, write time 4.5ms, max retries 0 === Move === DMs created 83, segments created 35, maxWait 39325768ms, bed compensation in use: mesh, comp offset 0.000 === MainDDARing === Scheduled moves 174944, completed 174944, hiccups 0, stepErrors 0, LaErrors 0, Underruns [0, 0, 3], CDDA state -1 === AuxDDARing === Scheduled moves 0, completed 0, hiccups 0, stepErrors 0, LaErrors 0, Underruns [0, 0, 0], CDDA state -1 === Heat === Bed heaters 0 -1 -1 -1, chamber heaters -1 -1 -1 -1, ordering errs 0 Heater 0 is on, I-accum = 0.4 Heater 1 is on, I-accum = 0.4 === GCodes === Segments left: 0 Movement lock held by null HTTP is idle in state(s) 0 Telnet is idle in state(s) 0 File is idle in state(s) 0 USB is idle in state(s) 0 Aux is idle in state(s) 0 Trigger is idle in state(s) 0 Queue is idle in state(s) 0 LCD is idle in state(s) 0 SBC is idle in state(s) 0 Daemon is idle in state(s) 0 Aux2 is idle in state(s) 0 Autopause is idle in state(s) 0 Code queue is empty === CAN === Messages queued 515965, received 0, lost 0, boc 0 Longest wait 0ms for reply type 0, peak Tx sync delay 0, free buffers 18 (min 18), ts 286648/0/0 Tx timeouts 0,0,286647,0,0,229316 last cancelled message type 4514 dest 127 === Network === Slowest loop: 204.72ms; fastest: 0.00ms Responder states: HTTP(0) HTTP(0) HTTP(0) HTTP(0) FTP(0) Telnet(0) HTTP sessions: 1 of 8 = WiFi = Network state is active WiFi module is connected to access point Failed messages: pending 0, notready 0, noresp 0 WiFi firmware version 1.27 WiFi MAC address f0:08:d1:02:e7:ad WiFi Vcc 3.33, reset reason Power up WiFi flash size 2097152, free heap 25112 WiFi IP address 192.168.1.17 WiFi signal strength -80dBm, mode 802.11n, reconnections 0, sleep mode modem Clock register 00002002 Socket states: 0 0 0 0 0 0 0 0 -
@Phaedrux
It appears to be cause by the bed mesh leveling.Is the z axis not able to keep up with the x and y moves?
Edit: This was indeed the problem. Thanks for the help.
-
Yes you figured out the stutter with the Z jerk.
I would seriously consider sticking with x16 microstepping with interpolation enabled.
