Creality CR-10 upgrade

dc42 · 10 Dec 2017, 14:16

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

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.

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.

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

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

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 · 11 Dec 2017, 17:37

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

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 · 19 Dec 2017, 16:07

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 :

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.

Agniusm · 8 Jan 2018, 18:33

I dont have that file. So G31 is the offset of the Z probe depending how its mounted?
So then i would go:
M208 S1 Z-3
Lower the nozzle to where it touches say piece of paper.
G92 Z0 to store that
But where is that offset, do i need to read it from web interface and then enter it to config.g's G31? Is there a step by step somewhere?

I suggest you read the commissioning instructions in the fitting instructions page, at https://miscsolutions.wordpress.com/mini-height-sensor-board/.

Agniusm · 9 Jan 2018, 11:28

Thank you. I think i have the idea now. Here is the map:

Is this any good or my bed is bad?
I have bought new 8mm precision plate but it does not look that precise.
Before i had Chaina heatbed out of 3mm aluminium and got this:

Can you help interpret the results?

P.S. I have 5V LED bar. Draws little over 1 A
Can i connect it to unused expansion header pins and control it with a macro? Cant seem to find header ratings

dc42 · 9 Jan 2018, 12:15

Your first height map looks OK, but the second (mostly red one) looks poor.

If you have a spare controlled fan output on the Duet, you can connect your lighting between +5V on the expansion header and FAN- on your chosen controlled fan output. The control it using M106. Or, if uou are not using the E1 heater output, you can connect the lighting between +5V on the expansion header and E1- on the E1 heater terminal block. Caution! Some versions of the Duet PCB have the E1- and VIN legends for the terminal block the wrong way round. E1- is the end farthest from the corner of the board.

Great. Thanks.

Agniusm,

I'm about to start my adventure to replace the cr-10 board with the DuetWiFi..
The steppermotor connectors are slightly different, but it's possible to plug it in…

Question:
Are the steppermotor connectors of the CR-10 pin-compatible with the connectors of the Duet board?
Can I plug them in the Duet board or do I have to rewire ??
If so, which way should the connector be orientated?

Agniusm · 14 Jan 2018, 14:30

I think you will need to rewire. I swapped my cables and built them from scratch so i don't really know.

tychop · 15 Jan 2018, 11:51

@Agniusm:

I think you will need to rewire. I swapped my cables and built them from scratch so i don't really know.

Not wat I was hoping for, but thanks for letting me know..
I'll go and hunt down the wiring of the cr-10 connectors.

dc42 · 15 Jan 2018, 13:19

You can test whether the connectors need to be rewired in either of two ways:

1. Use a multimeter to measure the resistance between pins. If the wiring is correct for the Duet, you should get a few ohms resistance between pins 1 and 2, and a few ohms between pins 3 and 4. There should be no continuity between 1 or 2 and 3 or 4.

2. If you don't have a multimeter, then you can try shorting pins together to see if it makes the motor harder to turn. If it is wired correctly, then if you short pins 1 and 2 together, or pins 3 and 4 together, it will be harder to spin the spindle with your fingers.
