Creality CR-10 upgrade

Agniusm

Started wiring. Got the X and Z working fine. Still need to wire in some end stops.
Do i need mechanical endstop on Z if i have IR bed probe?
The thing that buggers me though is the constant disconnect with message:
An AJAX error has been reported, so the current session has been terminated.
Please check if your printer is still on and try to connect again.
Error reason: timeout
Then i get:
Could not establish a connection to the Duet firmware! Please check your settings and try again.
After some refreshes it connects but it repeats.
I have read about signal strength but have no clue why, i think i have good connection, probably 6m away.

Updated firmware and interface, i don't know why some modules show as 1.19 when it should be 1.20:

Firmware Name: RepRapFirmware for Duet WiFi
Firmware Electronics: Duet WiFi 1.0
Firmware Version: 1.19 (2017-08-14)
WiFi Server Version: 1.19.2
Web Interface Version: 1.19.3

Dougal1957

beecause it hasn't taken the firmware try again make sure you are doing the right one?

Agniusm

OK. Tried this one more time and it updated. Now disconnects are rarer and reconnects faster. Still get them though

Agniusm

Stuck with mesh bed probing. I follow this:
Make sure there is no filament stuck to the nozzle (you may want to do this test with the nozzle hot)
Cancel any existing bed compensation by sending M561
Send M208 S1 Z-3 to temporarily allow Z moves down to Z=-3mm. This is to ensure that you can lower the nozzle all the way to the bed in step 5.
Command the print head to the XY coordinates you want to probe
Command the print head down in small steps until the nozzle just touches the bed or just grips a sheet of paper. You may need to send M564 S0 to allow movement lower than where the firmware thinks Z=0 is. You may also wish to create a macro to lower the head by e.g. 0.02mm to get greater accuracy (G91 followed by G1 Z-0.02).
Send G92 Z0 to define that height as Z=0
Command the nozzle up 5mm (G1 Z5)
Send G30 S-1 to probe the bed without resetting the Z=0 position
Read off the Z height from the web interface. That is the trigger height.

And get trigger height at 2.320
I put that value in config.g
G31 P500 X5 Y14.5 Z2.32
I don't know if i set the offsets correct. My probe is 5mm to the left of the nozzle and 14.5mm in front of the nozzle.
When i home, Z is at 2.32
The i do Mesh grid and send G29 but the bloody thing drives into the bed.
I am totally lost here

Check that you don't also have a config-override.g file with a G31 command in it.

The WiFi disconnects may be even rarer if you upgrade to 1.20RC1, but you may wish to defer that until you have everything working.

OK Everything works fine now. Trying to extrude. Doing extruder calibration. E3D states that their extruder is 400 steps but i only get half of the requested 100mm of filament. Will double the steps but why twice from stated 400? Could be voltage, that they state rate at 24V? Will see

P.S. BTW, any pointers where i can get sample start end end gcode scripts with mesh compensation?

The (approx.) 400 steps is for a 1.8deg extruder motor. You are probably using a 0.9 deg motor. If you bought it from E3D, it will be 0.9deg.

Agniusm

Ah, yes, you are correct, i completely forgot i've read somewhere about it.
I thank you David for your support and answering those noob questions. I can state that my build is alive and printing. Still some road to cover with fine tuning but i am so happy that i have completed this machine. Here is my 6th test cube:

P.S. I have noticed that each time i control printer through Panel Due i get ajax error on web interface.

dc42

Please report the text of the "Error reason" in the Ajax error message Z if there is one.

Agniusm

One general question. Trying printing quicker and i get some uneven perimeter lines. What could be happening? Does Extrusion Factor on web interface got anything to do with it?
My pressure advance is set to .7 on direct drive

M569 P1 S1 ; Drive 1 goes forwards
M569 P2 S0 ; Drive 2 goes forwards
M569 P3 S0 ; Drive 3 goes forwards

M203 X40000 Y40000 Z1000 E1200 ; Set maximum speeds (mm/min)
M201 X3000 Y1500 Z20 E250 ; Set accelerations (mm/s^2)

M906 X1000 Y1500 Z1000 E1200 I30 ; Set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout

dc42

If your extruder is direct drive (i.e. no significant length of Bowden tube between the extruder drive and the nozzle), then pressure advance of 0.7 is much too high. Try 0.05.

Agniusm

Tried 0.5 and 0.7 made it better. I found my problem. Skipping gear on e3d.
Don't know why its happening so will contact their support

Agniusm

What should i put in starting Gcode for mech bed compensation?
is it only the M28 command or should i erase previous probing?
Here is what i have at the moment (mainly modified from prusa mk2
M83 ; extruder relative mode
M104 S[first_layer_temperature] ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M109 S[first_layer_temperature] ; wait for extruder temp
G28 ; home all without mesh bed level
G32 ; mesh bed leveling
G1 Y20 X10 Z0.30 F7000.0 ; go outside printing area
G1 E10 F100
G1 X100.0 E9.0 F1000 ; intro line
G1 X180.0 E12.5 F1000 ; intro line

So instead of 5 point probing G32 i have, should i change to:
G29 S0 (or S1 if i want to use previous data from last measurement)?

So my titan aero is clicking and e3d sent a new motor only larger which does not fit my design. Are you David use titan aero and if so any issues ? I found this motor and i dont know if the data is correct and if it would work: https://www.omc-stepperonline.com/hybrid-stepper-motor/nema-17-bipolar-18deg-18ncm-255ozin-07a-29v-42x42x25mm-4-wires-17hs10-0704s.html

dc42

I don't use a Titan Aero, I use a regular Titan. The motor I use is this https://www.omc-stepperonline.com/hybrid-stepper-motor/nema-17-bipolar-18deg-22ncm-31ozin-133a-28v-42x42x34mm-4-wires-17hs13-1334s.html.

Changed my bed for precision plate now battling IR probe as endstop. I cant seem to grasp the concept here. I lover the nozzle to where it touches the piece of paper then G92 Z0 and when i home it does not go back to that height. Tried G31 P500 X5 Y14.5 Z-5.5 ; with no success.
Whats the proper procedure setting Z probe height?
I am looking at these :
https://duet3d.com/wiki/Setting_up_automatic_probing_of_the_print_bed
https://duet3d.com/wiki/Using_mesh_bed_compensation

dc42

The G31 Z parameter should be positive for sensors that trigger before the nozzle touches the bed. For the IR sensor is should be no higher than about 3mm.

If you are restarting the Duet between attempts, also check that you don't also have a G31 command in config-override.g.
