You can do that, just don't run G29.

Try setting extra restart and coast to end to zero. With pressure advance in use, you shouldn't need them.

@whosrdaddy:

No, if you map more drivers to the same axis, they automatically get the same current as the original driver.
You can specify a different current values per driver if you wish though…

Currently all drivers used by an axis have to use the same current.

i currently have the genuine e3d hotend with cartridge style thermistor…

Thks

Found one of the problems: E3d delivered me three 1,75mm nozzles where i ordered 3mm nozzles. The fact that i didn't use any 1,75 mm nozzles before i didn't notice the difference, i thought it was normal to have a bigger melting room with a bigger diameter. Because i ordered now 1,75mm nozzles, i noticed they were the same as some of my previous nozzles.

But because the supposed 3mm nozzles didn't work, i started modifying my heatsinks, I changed a direct drive to a bowden by adding a threaded clip on top of the direct drive heatsink. This didn't work out (ridge on the inside) so now i have two damaged heatsinks, and no working extruder. Also i just discovered that xl Bulldog extruders are delivered with too wide tubing. They deliver 6/4 mm for the 3mm filament and 5/3 mm for the 1,75mm filament, which makes the filament, specially for the 1,75mm filament blocking on the entrance of the heatsink.

Wiki has the answer…

M106 and M107

Sorry

FWIW, I do not have 'wipe with retract' on the machine used for this test: I've found if I'm using a volcano nozzle from .8-1.2, this has a large advantage in reducing blobbing from all the drool that falls out. But on .4-.6mm nozzles, not so much, and in fact, can actually make the print quality look worse in some cases, IMO.

But you bring up a good point: I've actually wondered (and not yet tested, although it would be easy) the same thing: If, in S3D, you have 'wipe with retract' set, but also enabled firmware retraction (via scripting solution of m101/m103) what would happen? Can you combine the two? I thought not, figuring S3D would be doing some sort of magic wipe/retract combo gcode, while firmware retraction (I presumed) 'just retracted', and had no concept of combining that with any other move at the time.

ok if i get it working i will let you know.

I'm using simplify3D. I have an extrusion of 1: 1. Only on the first and last layers I give 125% (infill only).

I have a long bowden tube (>800mm) and swapped to capricorn tubing and now use 5mm retraction @ 75mm/s with a small amount of extra length on resume I think 0.5mm, before that my retraction was all over the place and I really struggled to get it tuned, the downside was the titan couldn't push the filament hard enough for the new tube so I had to swap over to the Bondtech QR which has been awesome.

Have you considered where you're mounting the extruder? Can you get it closer in some way.

You need to change homey.g and the Y homing section of homeall.g too. See https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Cartesian_printer#Homing_X_and_Y.

Thanks!

I stopped at this configuration

[c]M92 X80 Y80 Z400 E254.5 ; Set steps per mm
M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation
M566 X1000 Y1000 Z400 E2400 ; Set maximum instantaneous speed changes (mm/min)
M203 X10000 Y10000 Z6000 E6000 ; Set maximum speeds (mm/min)
M201 X800 Y800 Z200 E1000 ; Set accelerations (mm/s^2)
M906 X1450 Y1450 Z1450 E1450 I15 ; Set motor currents (mA) and motor idle factor in per cent

For the test run from the console:

Works very gently.

so.. i made that calibration circle..and used this google sheet https://docs.google.com/spreadsheets/d/1HcnZ0aDC2wujHhPHVeYFcPekEpY6Y4wLSMfCxJ18e1o/edit#gid=1292102991 assumed lenght is 60mm
had on X 59,86 Y 59.39 and Z 59.41
had a R 99.275 and Rodlenght 212.782

after that print i changes Rodlenght to 211.727
and used M579 X0.725 Y-0.386 Z-0.339
saved with M500 and start to print another circle
Stopped it after first layer because it printed a oval with about 4x6cm

changing the diagonal rod only affects scale in all directions..so the M579 made a oval from a circle.. where did i make the mistake?

Spot on thanks

That suggests to me that your Z homing was not accurate before you ran G29.

The filenames are deployprobe.g and retractprobe.g and they belong in the /sys folder. So use the System Editor page of DWC to manage them.

It's ok to unplug a thermistor with the board turned on as long as you are careful not to short anything.

Bridging success with PLA depends much more on having a good print cooling setup than it does on temperature. If your prints are ok apart from bridging then there is probably nothing wrong with your printing temperature. To check the temperature using a thermocouple, feed the thermocouple into the hot end where the filament would normally go.
