Re: How many amps for old style 12v M2?

Thanks for the feedback Ed! And for the fair warning regarding the heater PSU. After melting 3 connectors I've actually given up on the heatbed, so now I almost exclusively print PLA on a bed coated with wood glue. The 12v heater took ages to heat up anyway, and finally caused enough trouble for me ...

How many amps for old style 12v M2?

It seems I'm on an unfortunate streak with my M2. As I was replacing the busted fan and my botched Y motor, the power supply unit died. No idea why, I disconnected it when I was doing any work on electronics, but it's clearly dead. Didn't occur to me for a while that this was the problem, so I had t...

Re: Uneven extrusion?

Didn't find any info on the motor itself. I checked around, and managed to find a similar-ish motor locally. It was a Wanhao Duplicator i3 Z-motor. The original motor didn't have a connector, the wires simply disappeared into the casing. So I had to cut the wires, and then figure out which wires wen...

Re: Replacement bed leveling compression springs

For future reference, I found replacements from Smalley with part number C056-H3. Not easy to order directly, but I managed to source a couple.

Re: Uneven extrusion?

After reading info on the MakerGear wiki for the first time in quite a while, I found: Check that the X and Y belts are the correct tension - with the bed or extruder at the opposite end of travel from the motor, pinch the belt together ~1 inch (25mm) from the edge of the motor drive pulley; it shou...

Uneven extrusion?

Hello, It's been a long time since I've posted here, but my trusty M2 (1. gen) is still with me. I've taken up a project that requires some level of accuracy, but something is amiss. My extrusions are really uneven. I'm attaching photos of a couple of prints as they look under a 20x microscope. Thos...

Replacement bed leveling compression springs

I have an early M2, I believe I've had it for 7 years now! I've unfortunately lost one of the compression springs located under the bed. I'm attaching a couple of pictures. Does anyone know where I can buy something like this, or what they are called? I bet makergear has replacements, but shipping a...

Re: saw tooth on smooth ramp

You could have a look at this stuff and see if it suits your needs. This article is fairly dated, you may find something newer of you look around.

Re: M2 Slic3r settings

Yes, you can remove runtatlin.sh from the postprocess setting. I'll update the config when I have time, it's a bit dated but tatlin was a workaround for older versions of Slic3r's lack of visualization.

Hotbed suddenly stopped working

I have a classic M2 with the dual power supply. I was happily printing on Sunday, but on Monday the heated bed didn't warm up, and it hasn't had any effect whatsoever since. I turn on the heat, and then there's no change in the temperature. The external big PSU for the heated bed (12V 18amp) has an ...
