Der DICE läuft... es gab noch Probleme mit der WLAN-Signalstärke wg.

>> @HaDe I saw you also complained about slippage in the spools, how did you solve it? << Guess I wrote about that in the list already but the problem was that the three original length clamping screws turned out to be too short.

hercek, appreciate your update, I admit I haven't followed recent firmware & fine tuning efforts too closely.

This sounds familiar somehow :-) ... as mentioned quite some time ago, I have the same symptoms here, though - luckily - not too serious so I can live with it. This is something even the mose careful calibration is unable to correct, and is caused by mechanical imperfections, usually towers not being spaced or angled perfectly.

>> Has any of you tried with that firmware? << Yes - but that was last November I think, and I definitely didn't notice any improvement in print quality or perceived smoothness of operation, but alas experienced the common problem of longer builds stopping at random positions after 2, 3 hours, so I switched back to Marlin.

Thanks for the update... looks fine!! Glad you to see you enjoy the 3DR as much as I do. Well, I also got into the FSR craze ;-) and have the FSRs (actually the smaller version with short leads) here ready to be integrated... but actually, as the bed levelling on my 3DR appears to be quite good and stable already, I'd rather spend my time designing my next printer - a corexy setup from which I dvon HaDe - Delta Machines

>> wont the PLA in the motor base soften with the motor heat in a long duration print ? << If the motor current is adjusted properly (only little is required, about 1/3 of the maximum setting), the motors only get slightly warm at maximum... they're way overdimensioned for the low moving mass of the 3DR.

I printed mine in PLA but don't remember the exact settings (50% - 0.2Z is what would use, too). I wouldn't worry about durability of the flex hinge too much, it will only be adjusted once and barely move during operation (provided your filament diameter remains fairly constant :-)von HaDe - Delta Machines

Hi... here are the weight figures: Non-Moving, original: steel rods 6/420 mm (2 x 94 g) = 188 g Non-Moving, modified: 300 mm rail (90 g), fasteners (36 g) = 126 g Moving, original: printed carriage, 2 bushings and magnet = 19.5 g Moving: modified: linear carriage, printed adapter plate and magnet = 21,5 g So this nets a substantial decrease in non-moving and, luckily, only a slight increase invon HaDe - Delta Machines

Always nice to see progress with those interesting machines... Pablo, I ran exactly into the same problem (incorrect settings for the printable area) when I struggled with my own 3DR buildup.

>> Should I try 32 microsteps? << As I just said, I didn't notice much difference.

Well one man's THING sure might differ from another man's THING :-) - but seriously I lost track of what everybody else did so I just took a little time and tested it for myself, both 16 and 32 microsteps - didn't see nor hear much difference so I simply stuck with 32 for higher (theroretical) resolution.von HaDe - Delta Machines

I assume we both use the same cheap chinese linar bearing bearings? :-) I found those to run a little rough at times, but not so much that it would cause binding and/or vibrations. In fact I bought more than required and selected those with NO slop. Those with slop caused noises and sometimes vibration - not constantly nor with constant frequency, but varying a great deal during printing moves.von HaDe - Delta Machines
Vibrations... some thoughts and experiences: - I usually adjust stepper current not by measuring but by adjusting by ear to obtain reasonable smooth operation (I ended up close to the middle position of the pots) - It pays to experiment with varying travel speeds (in the slicer settings) in order to stay clear of mechanical resonances - 200 mm/s works fine here - Delta segmentation in the firmvon HaDe - Delta Machines
Looks fine, congratulations! As for the bed heater: I use a quite lowly 17W circular heater foil which is barely enough to reach 60C - usually I print PLA at 50C. Insulation is 5mm cork. As for the bed: I tried several materials, including the Trinity Labs Borosilicate, which I found to be uneven so much that it had to be retired (see my earler posts in this thread).
