Re: Dolly Configuration

You don't want the probe to be quite flush with the end of the nozzle because there is a trigger distance, as slippy mentioned. And as you noted, there's concern with the probe dragging on the part, especially if any stringing or blobbing causes it to be sitting slightly higher than the current Z le...

Re: Need opinion

Seconded, I've switched to MKS Gen and 24v power for everything and I'm never looking back. Besides the technical benefits it's also a WAY easier board to physically work with, being far less of a crowded mess than a RAMPS shield. The XH connectors on the MKS Gen are also superior in every way to du...

Re: Dolly Build: Motor Stops Working with Reasonable Feedrates

Do you have a voltmeter to check the reference voltage on the driver? It should be insufficient current, which you can confirm by checking the vref on the driver, but it is also possible that it is a poorly crimped or attached connector. The motor is driven by sending power alternately to the two co...

Re: Creating Prusa(toms Dolly) design using aluminium frame. end stop question

I use Prusa Slic3r, it has every setting you need though I think it's not very user friendly at first. You can try Cura or if you want to pay, Simplify3D. The "Prusa PLA 1.75mm" preset setting in Prusa Slic3r is a good start to be able to print PLA properly right away. The only PLA-specific things y...

Ideally the belts should have tension as close as possible to each other, but I don't see any reason an overtightened X would cause this defect.

Re: Creating Prusa(toms Dolly) design using aluminium frame. end stop question

I just mean taking measurements at several points along the axis to confirm that it is not slanted. If you can confirm that your Y axis is parallel to your table by measuring it at several points, then you can use a square reference point on your table to check that the Z axis is perpendicular to it...

Re: Creating Prusa(toms Dolly) design using aluminium frame. end stop question

When you see very thin lines like that with gaps between them on the bottom layer, it means you are printing the first layer too high. The filament is falling a short distance and landing on the bed instead of being pressed into it and creating a solid fill. I am assuming you are leveling the bed wi...

Re: Creating Prusa(toms Dolly) design using aluminium frame. end stop question

Yes it definitely seems like your heatsink is too hot. The fan should run full speed the entire time the printer is on. The fan that blows on the heatsink should be connected directly to 12v power, not to the "fan" connector on the board, that connector is for the part cooling fan, if you have one. ...

Re: Creating Prusa(toms Dolly) design using aluminium frame. end stop question

Did you get any filament to push through? When you change from ABS to PLA, you need to keep the hotend at the ABS temperature at first to push out all the remaining ABS that is sitting in the nozzle. So I'd set the hotend to 230-240 and extrude until you get a decent amount to go through. This is ea...
