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...

Re: Precise printing thickness (print height)

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...

Re: Precise printing thickness (print height)

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. I'll do one, and then you do your experimentation. ;Sliced by ideaMaker 4.1.1.5050, 2021-06-13 20:11:4...

Re: Raise 3D Printer Help Needed

Well since it's an N series, and you replaced the motion control board, you did the throw money at it approach rather than understanding how it works and proper troubleshooting. The good news is, yes, I can save you a TON of money on the repair and do not replace the front panel touchscreen, that's ...

Re: Suddenly printing issues -- bumps & cracks

I'm trying to help but I have hit a a wall. I had the previous N series but not the pro2 series. I studied the pro2 series and did not buy it because of the price and mainly, the bad extruder design with lots of problem. See, the fix on an N series without moving nozzles is put a different compatibl...

Re: Scratched Y Rods

Oops, realized this is posted in an E2 topic.
Either way, the cause and repair is the same. The rod failed because the bearing failed. Always replace as a matched set.

Re: Scratched Y Rods

Not something to shrug off. You have a failed linear recirculating bearing in the central cross block and the hardened steel balls are harder than the shaft surface so guess which one wins? I had this exact failure on my N1. Yes, far out of warranty, but wasn't terribly expensive. Central crossing b...

Re: Precise printing thickness (print height)

Again, it's a simple mismatch of assumed coordinates. The printer thinks it's at Z=0 when homed, even though there is a mechanical Z gap intentionally set and needed by the printer for safe operation. WORSE, that gap is a variable set by the user's skill and variation from one printer to the next an...

Re: Precise printing thickness (print height)

What would cause the discrepancy of 0.305mm? 0mm height is the bed touching the nozzle. We cannot print like that and risk damage of an XY nozzle movement (example homing XY with the nozzle already touching the bed) while homed at TRUE Z0 so we "cheat" and make the Z homed position a gap ...

Re: Suddenly printing issues -- bumps & cracks

As to the mostly cosmetic upper deck panel attachment breaking- well that's due to the frame probably putting stress on it. You frame could just be slightly out of alignment or some issue, or it could be cracked from shipping damage. I'd say the mounting point is generally a weak point of the design...

Re: Suddenly printing issues -- bumps & cracks

Yes, replace the couplers and carry spares on hand. That is not a part to have break and is a wear and tear item.
They break because the motor to shaft alignment is not perfect.

Re: Unconsitant infill method on a round shape

Again, this is an expectations issue and misunderstanding of terminology and function. Gaps in infill settings has jack squat to do with the overall fundamental infill pattern used. It just means when it can in the pattern matchup THEN it uses single line. You'll notice the infill lines that are sin...

Re: Unconsitant infill method on a round shape

Because you chose LINEAR infill.
Yes, it's trying to fit the square linear infill in the proverbial round hole so yeah, exactly doing what you told it to do.
If you want ROUND concentric infill, then have have to choose that option.

Re: Precise printing thickness (print height)

Again, you have 3 basic errors or variables in final Z height of a print : First layer nozzle to bed mechanical gap - something you can adjust and correct. The problem is, you are taught and by the manual this is a number- say 0.1 or 0.2mm or some other value. It's a combination of how flat your bed...

Re: Suddenly printing issues -- bumps & cracks

Again, maybe it's just first layers and they print the same, but left looked bad, I mean pretty bad, and yes, with backlash motion, sure layers don't line up to previous layer as the per layer gcode pattern of infill changes, but it just seems worse than that. Again, expected pull in strands on a ci...

Re: Suddenly printing issues -- bumps & cracks

Broken coupler then if a circle isn't a circle. Kind of a known mechanical failure. I have to be honest though, I think you have more than one problem. The difference in just raw quality between the 2 extruders is not ideal. Since both extruders move together in XY, the motion problem and print not ...
