Re: kbob and Impulse, the Rostock MAX

If it was MY printer, I'd cut replace the crimp sockets - you may have a set that's simply out of spec. I say that because I've got three v1s (all are 2013 vintage) that I've nearly beaten to death and of all the issues I've had, a) all are my own damn fault and b) never a motor connection. Sometime...

Re: Rmax v.2 CURA?

The Cura profiles are more based on the hot end and max travel speeds. If you've got a v2 with the old 2-resistor style hot end, you can use the HE280 profile and tune the retract length & speed from there. The max travel speed should already be ok as all the HE280 equipped printers also use the...

Re: EZstruder "backslip" problem?

That's bad enough that I'd contact MatterHackers and see if they'll replace it. Right before I start using a new spool of material, I'll pull off about 3 meters of it and sample the diameter at at least 10 places and write the average down on the spool's label as well as the date that I opened the p...

Re: First homing: horrible grinding sounds

The chances that the hot end is to blame is vanishingly small. I printed four of the small two-post parts last night at 190C and there's no strings at all. You need a thermocouple to compare what the controller is reporting to what is actually going on. The most likely culprit here would be a thermi...

Re: EZstruder "backslip" problem?

You made no mention of under-extrusion in the original post. I'd be curious to see what the theory is behind chamfering the bowden tube. It kinda sounds like the 3D printer equivalent of wearing copper to fight arthritis. (looks nice, is complete bunk. :D ) If you've already calibrated your extruder...

Re: First homing: horrible grinding sounds

Try printing this file. It's currently printing on my machine without any stringing at all. I was getting some at 198, so I backed it off to 190. Stop trying to tear your hot end apart until you're positive it's the hot end. ;) (chances are that it's not the issue) A300_string-test-minimal.gcode g.

Re: First homing: horrible grinding sounds

If you're printing with the default SE300 Cura profiles, it's unlikely that you've got a retraction issue. I'd look at how hot you think you're printing vs how hot you're actually printing - test using a thermocouple. I'll try your gcode sample and let you know how it goes. [edit] I cut back the tem...

Re: EZstruder "backslip" problem?

It's called "skipping". It happens when the filament ins't able to flow through the hot end at the rate the extruder is driving it. The EZR is going to try to push the filament and it builds up compression in the bowden system until enough potential energy is built up that the stepper can ...

Re: Error: during calibration after print errors

Sometimes the FSRs get cranky when they're too warm. I haven't had the issue with my Artemis, but I've heard it happening to others. The simple solution is to just calibrate with the bed cold.

Re: Error: during calibration after print errors

Are you calibrating with the bed hot or cold?

I'd check to make sure that all the stepper motor connectors have their pins fully seated in the shells.

The only time I've seen layer skip like that is when the nozzle struck the print during a travel move. What slicer are you using?

Re: My printer has gotten an attitude.

Another big thing the DuetWifi has going for it are the stepper drivers. I've got one of them in Orange Menace - it's a Rostock MAX before there was a "v1" and it's a big echo box. It's nearly silent. I've got an 0.8.5 in another v1 and it's really loud - same drivers as the RAMBo.

Re: Artemis extruder calibration question

It's currently set at 182.0 - I've run close to 3kgs of filament through my Artemis and I've had zero issues that weren't attributable to a bad slice.

I'm using Cura 3.1 with the SE300 profiles from the git repo - my only changes have been to the temperatures used.

Re: Artemis extruder calibration question

Were you extruding from the Duet control panel? If so, what does "F30" or "F15" mean? Note that you don't calibrate the extruder by measuring output at the nozzle, you measure remove the bowden tube from the extruder and measure at the point where the filament exits the extruder....

You should've gotten a Duet. Unless it's been added recently, the firmware the Smoothieboard runs doesn't use the excellent calibration system that RepRapFirmware does. :)

That's some epic over-tightening there, Lou. :D The length of the t-slot isn't really that important - the critical dimension is the distance from the top of the bottom assembly to the bottom of the top assembly. That's why there are stop-screws installed to make sure that the distance is easily set...

Re: My printer has gotten an attitude.

I had another thought about this around 4am... the firmware may be smart enough to know that it can't move all three axes at the same time due to the higher steps per mm, so it may move a single axis at a time in order to reach the desired travel point.
