Re: Firmware 20170201 not valid for my MAX v2

Been wrestling with similar issues. installed a BLTouch on my V2 and its been working fine with older revisions, but not so much their latest. I know a lot has been customized, so I think my next step is to go vanilla Repetier and just transfer specific config settings I need over to keep it clean....

Re: Polyflex with Rostock Max V2

Seen your solution too - it appeared too complicated for me ;-)
The result with the simple approach I'm using is stunning. It prints really well with Polyflex.

Polyflex with Rostock Max V2

Just wanted to share the Extruder modification of my stock extruder on the Rostock MAx V2 when printing with flexible filaments like Polyflex: After jamming the filament indside the hobbed wheel - I've printed this modification on from Thingiverse. m It works really great !

Re: Smoothieboard question

I just realize that my board is not a original smoothieboard - it is a MKS sBase board. The "version" command doesn't exist here. Hmm.. Thanks for the config.txt file. You seem to use it on a Rostock Max - So I'll compare your settings once with my settings. I'll try the 50mm as well once ...

Re: Smoothieboard question

Thanks KAS.

I already have these values - and they seem to do the first bouncing to slowly approach the end stops. But they don't seem to have any effect after homing. My carriage remains at the end stops. Not sure why...

Any other idea?

Smoothieboard question

I'm currently testing a smoothieboard instead of the Rambo board on my Rostock MAX V2. I have a issue at the home all sequence at the endstops. On the Rambo board, after homing all towers, the carriage does a bounce back from 5mm with slow speed to the end stops. After touching the end stops again, ...

Re: Auto Calibration Requierments

I have 24 hrs of experience (literally just installed it yesterday) with the IR module and 1000s of hrs with FSRs so I am not qualified to comment yet. That said, every solution is a tradeoff. I like the concept of touchless probing but having the probe position offset from the nozzle tip is not id...

Re: under extrusion occurs every now and then...

I've printed the above yellow shell again with a different PLA filament (low cost PLA which gave me good results so far). (from m). It's the outer shell. Strangely I've found some irregularities similar, but not identical to what I've seen on the yellow part already. I decided to print it out again ...

Re: under extrusion occurs every now and then...

Happens on expensive PLA (Dutch filament) and also low cost type PLA filament.
Didn't happen in the past, but now as shown from time to time in middle of a print.

General question: Is this problem more related to the hot end or the extruder / hobbed bolt?

Check whether your glass plate is still flat. Mine seems rather tilted - and I don't know why. It's just like a 'chinese hat' - higher in the center.

There's no belt alignment issue because you move the gear to offset the thickness of the damper. g. Nope - nothing at all. I was concerned about this too, but the gear rotates accurate on the "shorter" motor axle. Print outs come out well - or even better. At least they are being printed ...
