Re: Extruder Problem feeder. Kracking noise

You probably do not need to replace parts. You do need to open the extruder and find out what is likely jamming the gear set and fix that. Probably a loose setscrew or other minor issue. Seen here before https://forum.raise3d.com/viewtopic.php?t=15292 Pro2 alignment setscrew Bondtech.jpg Otherwise, ...

Re: Second Layer Z Shift

Raised. Increasing this value increases the nozzle height above the previous layer to cause the nozzle to drool rather than squish this layer into the previous layer. However- let's not do it this way!!! Let's get better at understanding ALL the variables and the better ways of handling the problem....

Re: Major mechanical Failure

You don't need to remove/loosen any couplers to move any axis. With power off, they are just direct drive stepper motors that can be turned by hand without any special effort.

It's bad enough he has to rebuild the hotend- let's not take apart unnecessary axis parts just to move something manually.

Re: Major mechanical Failure

He may not be able to do that if when it dragged the extruder head out and pulled on the wiring it likely ripped out the thermocouple temperature sensor. That forces the firmware into thermal shutdown and NO commands can be sent, nor can you do much of anything from the control panel. Good luck, pow...

Re: problem with the infill

Also, while the last post focussed on the hotend and nozzle system as a constraint or limitation- the extruder is a system of components, so cooling of the cold section of the heat break or throat tube is one component, as is the entire feeder mechanism, everything from the motor to the gear train a...

Re: problem with the infill

Again, extruders have multiple limits, one of them being an important one- sustained extrusion rate. Sustained- meaning where line in infill, you are doing long lines of extrusion back and forth without retractions or traveling moves which to he extruder is basically one really long line of fast ext...

Re: E2 control button bug

You got told the answer and yet don't comprehend. The screen does NOT directly control printer hardware. There are 2 completely separate processors in this printer one running the screen and SENDING gcode commands- the other the motion control board READING and EXECUTING gcode commands that actually...

Re: Pro 2 Plus Z-Axil faliure

The Z axis does have a motor to shaft coupler https://forum.raise3d.com/viewtopic.php?t=4268#p20717 just like X an Y axis, and sure, that coupler could break. The idea is that if manual jogging works via the raisetouch panel- then probably not the coupler. If the axis moves wonky- example one direct...

If the bed can be moved up and down via the raistouch manual jogging commands- again both up and down- motion control is working. If the bed only moves down and not up or cannot be homed up and reach the home position- suspected Z homing/limit switch stuck or failed. In a Pro2 it's an "optical&...

Re: Pro 2 Plus Z-Axil faliure

OK, so what you are implying is that the printer is NOT following the printing gcode. That's not a good starting point in troubleshooting. Again, the basics, this is a 2 board control system. The front panel raisetouch is a print server streaming gcode with a user interface for limited manual comman...

Re: Missing pin or not ?

No, that is an intentionally missing pin to form a KEY so that the mating ribbon cable connector that ALSO has a pin jammed into the matching hole cannot be plugged in backwards.

Re: Precise printing thickness (print height)

The lessons to be learned: #1 this slicer (Ideamaker) and many others do not account for the mechanical homing based nozzle to bed gap. #2 First layer settings aren't complicated, it simply puts that value for the first layer move from HOMED position. As seen in #1 homed position probably isn't true...

Re: Precise printing thickness (print height)

What would cause the discrepancy of 0.305mm? Answer: a rather tall adjusted first layer gap of 0.28mm to start with. the Homed clearance of the nozzles over the print bed is set at 0.28mm rather than the default 0.20mm to cure an over-adhesion problem And then, adding an extra tall layer well outsi...

I said before that the Homed clearance of the nozzles over the print bed is set at 0.28mm rather than the default 0.20mm to cure an over-adhesion problem. Wrong, you should adjust first layer flowrate to adjust an over extrusion problem if you know the gap is right . I also said that I had adjusted...

I want to help but part of this is you learning yourself. That means reading gcode. That's not too hard, we are looking for a single line and really a value a Z axis value AFTER the starting gcode.
