Re: Z home acts weird - 9 years ago
I have very limited knowledge about this but I think your accelerations look very high. Try lowering them, I think I saw somewhere that a setting of 1000 is a good start, you can increase it later.by Koenig - Delta Machines
Re: just installed duet and no good joy for me - 9 years ago
Quotethetazzbot Printer was printing fine with ultimaker arduino combo but I wanted "modern electronics"... So i upgraded to duet and dc42 firmware and spent two solid days trying to get a print. Travles are nice and smooth, endstops correctly set. Motor current set at 650. Belts tight everything normal but the layers are aweful and look like my prusa when it skips and shifts the layers.

QuoteJ-Max Hi again, I print ABS @235°C and teflon does not matter. Maybe if you print nylon or PETG ? ++JM I think PTFE is good up to 240°C, if you are going to print something hotter you need to go all metal. Reference for the temperature:by Koenig - Reprappers
Re: Benefits / Drawbacks of Metal Effector Plates - 9 years ago
First thing that comes to my mind is you get better stability of the hotend at higher speeds/accelerations. Might be wrong about this though. Gonna try for my self, ordered a metal effector from robotdigg a couple of days ago. I would like to see a metal effector that goes with balls/magnets though, where you fasten the balls to the effector and have the magnet inside a PTFE-cone on the rod.by Koenig - Delta Machines

Re: simplify 3d help - 9 years ago
Don't really see it on that photo, it's kind of blurry. Anyway, if it's not a printer-error you can activate "Allow gap fill when necessary" under the "advanced" tab. That is a setting that fills small gaps on thin walls if the perimeters are not wide enough to fill all.by Koenig - Printing
Re: weird side effect from retraction - 9 years ago
This with 0 Z-lift tends to give other problems though. The fine stringing that always is there with PETG tends to accumulate on the nozzle to the point that it leaves a small blob somewhere. With Z-lift enabled this mostly happend so it would leave the blob right outside a perimeter so that the nozzle on the next pass just gently pushed it aside, but with no lift it leaves the blob right in theby Koenig - Printing

Re: Fan duct for kossel mini - 9 years ago
QuoteDragoslaV I believe with Olaf's design the air can only escape trough the bottom, therefor cooling the object. That is a really neat concept. I don't really think that, it would the blow straight on the heater block, which then would make it real hard to get working temperate. I would rather think that one "hole" should be left open or that the fan should be mounted the other way round inby Koenig - Delta Machines

Re: floating G29, or crashing into bed - 9 years ago
QuoteSintensity QuoteKoenig You have calibrated your printer? I might be wrong here, but I think you must calibrate the printer before performing any bed level probing.

Re: Extrusion Rate Changing - 9 years ago
Quotekelen87 Thanks for the response! The fan cooling the hot end down did come to mind. But when I look at the extruder gear while printing it goes at a slow "normal speed" during perimeters. But during the infill process you can see the gear has drastically sped up. I wouldn't think you'd be able to see full revolutions of the gear within a couple seconds, even if my hot end is indeed hot enouby Koenig - Reprappers

Re: weird side effect from retraction - 9 years ago
I've been playing around some earlier trying to get that smooth surface of PETG, and I've also found that lowering the temp or aiming for slight overextrusion helps a little. I guess both ways actually does the same, raise the pressure in the nozzle. But this certainly makes a huge difference. Good find I'll have to say, and thanks for sharing.by Koenig - Printing
Re: Calibration Issues - 9 years ago
Which electronics are you using? If you are on RAMPS it sounds like you forgot to install the small jumpers underneath the drivers or possibly installed them the wrong way. Those jumpers activate different modes of microstepping, if not installed the motors will only do full steps.by Koenig - General
Re: weird side effect from retraction - 9 years ago
QuoteDownunder35m Also the speed for the retraction should always be a bit slower than what you can extrude without problems. Otherwise all you do is eating filament... I don't quite follow you here. I usually retract with 70-80mm/s at an acceleration of 3600mm/s² That is much faster than I can extrude, if I try to extrude that fast it starts skipping steps. I could probably go way higher in tby Koenig - Printing
Re: Kossel 2020 delta printer - auto Z probe tuning - 9 years ago
Quotedjtrance2 Thanks for the link. This is very good procedure. However, there is one part that seems a bit difficult: 1- it seems we need to adjust for the tower endstops manually using the screws that fasten the endstops to the extrusion aluminium. I can see 0.3mm adjustments to be very difficult to do by hand, are there setinngs in the firmware to adjust those distances instead? You can useby Koenig - Reprappers

Quotedc42 In response to more than one post above: 1. If you want to achieve the effect of moving the X tower a little closer to the centre, you can achieve that as follows. Your towers form an isosceles triangle instead of an equilateral one, with the base longer than the sides.

Re: weird side effect from retraction - 9 years ago
I have noticed I get a lot of blobbing if I don't use retraction when printing PETG (leaky e3d v5 clone), but as you say it introduces small bubbles in the print. how much retraction did you end up with? I was perhaps thinking that some extra start-length after retraction would help as well.by Koenig - Printing
Re: New RepRapFirmware 1.09i-dc42 for Duet electronics - 9 years ago
Quotepkm Koenig I agree with David here. Angular positions + delta radius + origin shift is identical to tower offsets + delta radius. But nevertheless you don't get the result. I would try another set of calibration points, different number of points etc. You are totally right, this is what I'm asking for here. Just that you cannot set this in reprap firmware at the moment.

Quotedc42 I suspect the problem you are having with XY ratio not being correct is due to backlash in your joints, or one pair of diagonal rods having unequal spacings at the upper and lower ends, or diagonal rods being not quite the same lengths, or something similar.
