What happened? Seems like the last 2 posts from me and fotomas are deleted... Anyway, the thing is that after a successful "coat hanger" print the problem has come back. The first layer looks very thin by the way so I increased the extruder percent from 100% to 110% on the fly, but I now think that's not the way to solve the problem. Any ideas? Maybe try to increase z height a bit more? So, shoby kpapr1 - Ormerod
Thanks fotomas, I was just about to ask for advice again because after a successful "coat hanger" yesterday (really nice print - almost perfect) I got the same problem again today while printing "ormaxis". I have noticed the first layer was quite thin so I thought maybe it was under-extruding and changed it to 110% on the fly from the web interface. I have calibrated the z-axis and I get 1.5mm foby kpapr1 - Ormerod
OK, I re-adjusted the z-axis and it proved to be a bit too low, so everything is fine now at last :-) Thank you all for your help!by kpapr1 - Ormerod
The hobbed wheel spins freely. I will check the z-axis again tomorrow - too late now - and report back. Maybe it needs calibration after a few crashes while upgrading to the new firmware 1.09o-dc42. Thank you all for your input :-)by kpapr1 - Ormerod
Hi Eric, My filament looks just like yours, except of course the parts where it has been filed by the hobbed part. The bearing is there, too. I also turned the extruder big gear by hand and it runs smoothly (with e-motors off). I had problem with this in the past but I filed the gears and now it is very smooth.by kpapr1 - Ormerod
Hi, I have now gained a bit of experience now (fairly new user) and have calibrated and fixed some problems but I'm really stuck on this one. What happens is that after some time the filament stops being fed into the nozzle. I have examined the filament and it seems that the hobbed insert has eventually filed the filament. So this is what I have tried so far. 1) Removed bowden tube from the Quby kpapr1 - Ormerod
It's OK as long as people know, maybe add it in the documentation for now.by kpapr1 - Ormerod
AT LAST !!!!!!!!! It finally worked, I don't know if it's important to put the points in a clockwise manner, but it now works! THANK YOU ALL OF YOU FOR YOUR HELP :-) Too late now to print, going to sleep and trying a print tomorrow.

I tried correcting the X Y values in order to create a rectangular --> no luck I tried putting S0 in the end like Darathy's bed.g file --> no luck But at least we have spotted the problem :-) So it will be solved sooner or later... I'm currently using firmware 1.09o-dc42by kpapr1 - Ormerod
I found this: dc42 [ PM ] Re: New firmware 1.09k-dc42 October 09, 2015 02:31PM Registered: 2 years ago Posts: 8,344 Thanks, looks like the firmware is producing a spurious message when you use S0 or just S on the last G30 command. Changing to to S5 (as you have 5 probe points in the file) will probably avoid it. But I'll investigate it with a view to implementing a fix in the next release. Cby kpapr1 - Ormerod

Yes, the sound is probably coming from the PS, but why only when doing auto bed compensation? and always at exactly the same time? I have been printing (well, testing and solving problems really) for a while with no problem from the PS. This is strange. 2 and 3 hour prints complete without any problem from the PS. I will run the bed.g commands manually one-by-one and see which command causes theby kpapr1 - Ormerod
Updated web interface files on the SD card with latest (I think I had already done that), also cleaned cookies from Chrome browser, AJAX error still there. Just after bed compensation is done. I also hear a bleeping sound at that point from the printer not sure from where, but it's not from the PC...by kpapr1 - Ormerod
OK, I have discovered that M558 P1 works for me, this means I don't have a differential probe, but M558 P2 worked in 1.09 version (I was getting 2 values - one inside parenthesis, now I only get one value and z-homing works)... ... BUT after auto bed compensation I still get the AJAX error, any ideas about that?by kpapr1 - Ormerod
It seems the z-axis IR sensor is not taken into account... although I can see from the web interface that the values are changing while altering the height. I have copied these commands from my old 1.09 version firmware into the new (1.09-dc42) config.g file, where the z-axis homing was working G31 Z0.80 P602 ; Set the probe height and threshold (put your own values here)by kpapr1 - Ormerod
Thanks dc42! May I also ask why there's no bed.g file in your firmware? Is it ok if I put the bed.g commands from the 1.09 firmware into the new dc42 config.g file? Will bed compensation work like that? At the moment during z axis homing the head crashes into the bed and the motor keeps lowering the head until I manually stop it.by kpapr1 - Ormerod
Oh now I see, I need to change the value in the config.g file. The default value in the dc42 firmware is R1000 so I need to change this to R4700. Thanks a lot for your help!by kpapr1 - Ormerod
Yes, the resistors are indeed 4K7, I bought the printer in September 2015. Regarding the firmware I was using RepRapFirmware-1.09 and besides the AJAX error during auto bed compensation all else worked fine. I think I will switch back to RepRapFirmware-1.09 and try to solve the AJAX error Thanks for your help!by kpapr1 - Ormerod
Hi, My original problem was that when trying to do an auto bed compensation the web interface would always crash with a AJAX error straight after the termination of the calibration process (Windows 8 - tried Chrome-Waterfox-Explorer all the same result). Reading several posts on the forum I thought I might try to upgrade to 1.09k-dc42, but as soon as I opened the web interface I saw the wrong tby kpapr1 - Ormerod
Thanks a lot Darathy for your help and advice! I have started a new print and the fan is now on right from the beginning and the overhang looks good now!by kpapr1 - Ormerod
Looking at the gcode generated by slic3r I find the M106 at line 3200 out of around 47000 lines. This means that the fan is not activated for the overhang layers printed in the very beginning. I can tweak the code manually but is this the right method? I did find the fan settings - I had to switch to advanced mode. Let's see....by kpapr1 - Ormerod
If I understand well it's the one that is activated using the M106 command. This is not included in the initialization code the slic3r generates. Should I insert it manually?by kpapr1 - Ormerod
Sorry, NOT the hot-end fan - this working fine, I mean the part cooling fan.by kpapr1 - Ormerod
OK now that I stopped printing and letting everything cool down the fan is on! (yes, the fan on the hot end). But why the fan is off while printing? Do I need to set it in Slic3r manually?by kpapr1 - Ormerod
Damn, I just noticed that the cooling fan for the part is not working (I have placed the ormerod inside my firing place so it's not visible easily). But in previous tests it worked. Should I manually enable it before every print begins or should this be done automatically?by kpapr1 - Ormerod
Yes, I have the acrylic fan spacer.by kpapr1 - Ormerod
Thanks for your reply, I do have some spare fans but I'm not sure if I can mount one like in the pic but I will try. So you think the problem is that the overhangs needs extra cooling? Yes you are right this is the bottom side. Maybe it's possible to set a delay parameter so that each layer gets some extra cooling? I will try for now to add an external fan that continuously blows on the printed pby kpapr1 - Ormerod
Hi everyone, I'm fairly new to 3D printing and only recently have I finally managed to solve all major issues I had with the ormerod 2 printer. I have managed to successfully print the snowman, but trying to print one of my own designs (volume knob) I see new problems arising. Looking at the picture you can see material missing from some areas and the curved area of the volume knob not being a cby kpapr1 - Ormerod
OK thank you *Update: the problem was that I updated the uController firmware without updating my SD card :-)by kpapr1 - Printing
Hi, I'm new to the 3D printing world and I have just assembled an Ormerod 2. I have run all checks (proximity sensor, nozzle heats up, fans work OK, xyz movement, temperature reports OK, bed heats up, all motors work fine) but the problem is this: When I try to print snowman for example, the printer does its calibration on the 4 corners where the white papers are and then moves to a position thby kpapr1 - Printing
