Re: Changing the nozzle @ N2

One suggestion, look and see and make a note of where the fans connect to the breakout board and then UNPLUG them before working on the hotend. It is so very easy to slip and ruin a fan when removing those fan screws

Re: Bad surface of layer on the underside of prints - what can be the reason?

another tip, especially with a curved bottom surface, is lift the entire model at least 10mm in Z and completely cover it with support, This way the support is at least 10mm thick and is more stable than the short supports people often make.

Re: remote raised 3D ? wifi ?

Some people use octoprint with these printers but you have to plug the usb from the octoprint directly into the motion controller board and then you can't use the front panel

Re: Raise touch release info

I believe he is asking if the updates are cumulative.

I'm pretty sure that each update is the complete code and the latest one is all you need.

Re: Z-position, Vertical and horizontal Offset, Line Support

for first layer, there is a setting for first layer height. What it should be is a bit controversial and people swear by anything from 75-150% of layer height.

I'm surprised by the lateral offset, that may be a bug.

Re: Strange Print Failure - Mystery?

that was most likely from a head strike, these occur quite often with pla due to edge curl. make sure cooling fan is uncovered and insulating the hotend can help quite a bit.

Re: Bondtech Upgrade - Z Axis Issue

remember grinding can also mean high back pressure. change out to a new nozzle and perhaps raise the temp. I find that the optimal temp varies quite a bit among different rolls of petg.

Re: Grease ?

contact raise, they have a procedure written up, iirc. Move around the head with steppers disengaged and see if there is any binding.

btw you do need SOME grease to prevent corrosion

Re: New to 3d printing, struggling with print

one trick is to use a raft if using support and lift the whole model 1cm so the support is continuous under the model. This actually makes it easier to remove (short support is a bear) and makes for a better surface as there is less rocking of the model while printing.

btw, insulate your hot end.

Re: extruder pausing after retract for restart

BTW our printers have direct drive, not Bowden and need significantly less retraction, eg 1.5mm.

Re: New to 3d printing, struggling with print

see how the edge slopes on the right print? That often causes pla to curl upward leading to a head strike. You may want to insulate your hotend to prevent that.

Re: Retraction settings HELP!

if you are getting gaps you may need to set extrude extra on restart or something like that. I had to use about 1mm when printing petg at lower temperatures after it retracted - test using retraction tests.

Re: Temoerature Not Rising

thermocouples are very interesting things. They are made of a springy form of steel wire! They cant be soldered normally and are held into screw terminals in a clamping action. One of mine broke, but because the wire is so springy, it maintained contact with the terminal most of the time, most but n...
