Welcome to the SeeMeCNC Community

Thanks! Yes .5 nozzle and repetier firmware and host. I print the first layer and then turn on three 40mm fans (wait till you see my fan mount accessory!). This is 1.75mm PLA. Thanks! I'll post pics of my fans as well (I am using os1r1s mounts with 2 squirrel fans) . I'd love to see how you have yo...

That looks awesome! I am going to try your settings and see if I can replicate. I have a few questions. Did you use a fan at all to cool the PLA? Are you using Repetier firmware? Are you using the default 0.5mm nozzle (I would think you are from your kiss settings). Are you using 1.75mm PLA? Again I...

Part of the problem I am having is that I cant get a reliable retraction speed above 30mm/s that does not occasionally skip a step. This is even with my stepper digipot set to 255. I think I need to get to at least 60mm/s to start improving things.

Agreed! Do any of your Cartesian printers have a Bowden? That has been the biggest challenge for me. A direct extruder is "crisp" in its retraction, the Bowden tube introduces some slop. No this is the first bowden I've played with. I'm at 10mm for retraction right now. On my cartesian I ...

I'm still not happy with it. I won't be until I can get it to print as nice as my cartesians.

I think ABS would be easier. PLA is very hard.

Hey Guys!

Its taken many attempts but here is where I'm at now. Printed with black PLA.

- 0.25mm layer
- 0.35mm nozzle / 188C
- KISS Slicer

Even though I have calibrated my filament I think I am still a tiny but heavy.

Hi Guys, I've been working on printing PLA and I am tuning the settings. Right now my retraction speed is 30mm/s with 4500 for accel. I am running Rambo 1.1 and the current is set to 235 (digipot for stepper current) for the extruder. I'm finding anything above 30mm/s and I will get missed steps. Th...

In preparation for my Rostock Max tuning I have been tweaking os1r1s's mm2 KISS settings for use on my behemoth. I printed out the pyramid again to use as a reference. I am planning on using KISS slicer with the Rostock Max. Picture attached.

This challenge is only for Rostock Max. Edit: Actually any Rostock

I've printed this thing on 3 different printers and I've never been able to match the quality in that first picture, I can't cool the struts fast enough tha they don't get pushed around, and I can't get a clean point on top, I'd be interested in what settings and what hot end was used for the pyram...

How did you make out?

Could someone post the slicer settings to print that out on the Rostock Max? The picture was from the reprap wiki ( http://reprap.org/wiki/Rostock_MAX )... here is the text for the settings used: The following settings were used to calibrate retraction on the hollower pyramid thing at http://www.th...

Thanks and yes I've posted a fair amount on that forum about my g0704 cnc mill conversion. I'm glad you are up for the challenge and I look forward to seeing your results

Hey Everyone, My my Rostock Max kit is in the mail...yahoo! I've built many repraps and have even designed my own printer (behemoth http://xnaron.com). I'm looking forward to getting my romax up and running as soon as it arrives. I printed out a Hollow Calibration Pyramid on my behemoth to help me t...
