Re: Messy horizontal surfaces

Also, a good time to get your starting and ending gcode corrected and stop guessing what flow rate the printer is using and know you are starting with 100%. Suggest reading this entire topic (multiple posts) to understand the complexity and remedies (editing starting and ending gcode default sequenc...

Re: N1 Dual Bondtech - turns off trying to start printing

As to the why it would do what you are saying: If the PSU was set for 220V expected, but only provided 110V, then since it is a switching supply, the PSU can put out the regulated voltage of 24V at low power draw situations, however, when the heaters kick on during a print job or preheating- specifi...

Re: N1 Dual Bondtech - turns off trying to start printing

Have you switched the PSU to the correct voltage???
There is a switch inside the power supply and it is not trivial to reach or validate that switch.

Re: Help Understanding Extrusion Rates

I am having issues with extruding ABS at 240 C. I got horrible under extrusion with my ABS settings in Ideamaker. I tried a manual extrusion of 100 mm. I initially set the flow rate to 300 (G1 E100 F300). The printer only extruded 90 mm. With PLA it extrudes 100 mm at my current firmware E step set...

Re: Help Understanding Extrusion Rates

And yes, let's also explain what you were doing in the first post. You were changing feed rate while testing (but thinking or calling it flow rate). You discovered, that per testing, feed rate can affect extrusion distance accuracy when we go faster, this causes more back pressure in the nozzle and ...

Re: Help Understanding Extrusion Rates

So, with the above info, let's correct this. #1 Highly suggest you go into your profiles and add proper end code to reset the flowrate on all prints to 100% at the end of the job so the machine results in a KNOWN default state instead of the current method which leaves the machine in an unknown stat...

First, appears to be some mistakes in the gcode and terminology in general. Syntax is: Command Axis Distance Feed rate Or sometimes Command Axis Parameter G1 is the command- coordinated move aka extruding move because we have an E axis distance E100 is 100mm is distance for E F is feed rate- the rat...

Re: Why two settings for Layer Height?

Again, just some basics. What is a raft? An artificially thick first layer printed on first layer and then the slicer adds the print as the next layers to provide compensation for poor leveling and first layer gap. Or, skip the raft and just make first layer a fixed height. What are the general pros...

Re: Why two settings for Layer Height?

First layer depends on how well your bed is level and Z gap when home is adjusted. Example is, let's say your bed isn't super level or perfectly flat. Use a larger first layer so that there is room to comensate for the unlevelness. Then you can use a lower layer height for the rest of the print for ...

GT2 belt, however, they are open loop- hence why there are no numbers for length, cut to length.
Again nothing more than gt2 2mm pitch, 6mm wide.

Re: N2+ no motor movement

Just on a whim before blowing a lot of money replacing I board, I would have long ago plugged in a less than $20 direct LCD control panel (since this is an N series and that is supported) and commanded the board and firmware directly for more accurate troubleshooting.

Re: N2+ no motor movement

The lights just indicate when the console is sending or receiving gcode. If no commands are being sent, the chatter is just temperature reporting back to the LCD control subsystem. That said, again, if the stepper drivers died, the board likely died with it. So replacing everything isn't the worst i...

Yes. I wish that I could share my level of knowledge of the machine with you. The front panel is nothing more than a gcode streaming console, not unlike Octoprint.

Other examples would be shell, first layer, bridges, roofs, floors, support and so on that have defined values or when...

Re: Should these be loose?

Re: Should these be loose?

OK, so kind of a major issue in false diagnosis, that is not Z banding caused by a lead screw. What you have is some form of backlash (AKA lost motion) in the XY system and that presents itself when the pattern of motion changes as the print gets taller. Again that's not Z wobble, that's XY motion b...
