Marlin will never be fixed Do you use z-lift during retraction and UBL at the same time?by o_lampe - Printing
Count me in, but I believe we can't focus on plastics alone. As said above: the earth needs a 'green revolution'. Poititians and lobbyists won't help at all. I've seen a guy on an island, who builds boats from waste plastic, but that's not enough. Problem is, that during crude oil cracking, we can't choose what to produce. We get all the stuff from heavy oil for ships to kerosine for planes. Juby o_lampe - green talk
Looks good! I think the clamps for the X-rods could be a bit beefier. Also the brackets for the idlers look like they could suffer from layer separation one day. Is there a chance to change print orentation? You could also try to decrease the distance from idler to Y-rod. Even if the printer won't gain print volume: the shorter/the better.by o_lampe - CoreXY Machines
There are DXF files for Prusa frames around. You can ask the local machine shop to cut it for you. Another option is Orballo in Spain.by o_lampe - Prusa i3 and variants
I always put a line like G92 Z### in my Slic3r startcode. That way it is 'permanent' but still adjustable. Once you've found the true offset, you can edit Marlins Z-probe offset accordingly.by o_lampe - Prusa i3 and variants
There is a temp range, where PETG is pretty cheesy. Printing at lower temps let the string rip apart. Printing at higher temps builds a small blob. I'd try 230-235°C for a change.by o_lampe - Printing
Maybe something went wrong with hardware retraction? What, if you send G1 E-5 F### instead? As a general advice, it's always useful to erase the EEprom before flashing a new Marlin version. HTH Olafby o_lampe - Printing
It really looks great! What causes the pauses at the corners? Is jerk setting too low or does the magnet move but it takes a while for the ball to follow? ( square mag/round ball issue we discussed earlier ) edit: I didn't watch the first test... video before, but the pulsing movement seems to be related to unfocussed mag-forces?by o_lampe - CoreXY Machines
You can always use RAMPS_test.ino to see if hardware is working. It doesn't care about endstops or extruder temps, so it's better to have the steppers run free. ( no belt, no filament )by o_lampe - RAMPS Electronics
There are three parameters that regulate extrusion: 1. filament diameter 2. extrusion multiplier ( yours is set to 1.1 ) 3. e-steps I usually measure filament diameter and set the value spot on, same to e-steps calibration. From there, I only play with extrusion multiplier to fine tune the print, where I tend to slightly under extrude.by o_lampe - Printing
Set Slic3r to output Marlin-flavour and tell Duet to act like Marlin. M555 P2 ; Set output to look like Marlin The rest is in the start/end code as you said.by o_lampe - Duet
Looks nice! You have a fixed bed and the gantry moves in Z? How much does the gantry-belt tension bent the vertikal pipes inward at half_height?by o_lampe - CoreXY Machines
Now it seems right, but the kinematic is a mix of H-Bot and CoreXY. dX = dA ( red belt ) dY = -dA + dB ( blue ) I don't know if it's worth adding extra length to the blue belt and get more stretch/ringing there, just to fight extruder tilt. ( which is neglectible when using linear rails and carriers) edit: I just saw that both belts are equal length, so forget my above comment. It's even worsby o_lampe - General New Machines Topics
There's an error in your drawing. I marked the belt in question with a red arrow. It is fixed in length and hinder the gantry to move 'down' or it'll go slack, when moving 'up'by o_lampe - General New Machines Topics
QuoteI would guess there is much more knowledge about Marlin out there though. Compared to RRF, there are way more threads about Marlin stuff, but that's mainly because configuration is so messy. Try out RRF and you'll never look back.by o_lampe - Prusa i3 and variants
Maybe your leadscrews and the acrylic frame are too noisy for an underbed Piezo? I had to adjust my sensor to 'almost def' and then got into the same missed trigger issues as you did.by o_lampe - Reprappers
You can wrap aluminum foil around the sensor head. That puts the sensor closer to it's triggerpoint and increases triggerheight. If the foil is too low, the sensor already triggers in free air. Use the threads of the sensor to adjust foil height until it just doesn't trigger. Maybe you also have to use thinner glass or a thicker heatspreader.by o_lampe - General
You might find the 2130 aren't super quiet on 12V. They really get better on 24V.by o_lampe - Prusa i3 and variants
AFAIK, the LCD has a 5V_to_3.3V regulator onboard. With this bypassed regulator ( shorted ) it should work without any levelshifting.by o_lampe - RAMPS Electronics
I made a T-slot slider using Delrin-rods as inserts. It is way cheaper than Igus-filament and very precise. You can also use PTFE-rods, but they are pricey and less durable. ( they slide a bit better, tho ) This is an older pic for a different extrusion I started a thread in the 'Delta' section about my "compact carrier". Ignore the belt-clamps. The latest version has adjustable tension, whiby o_lampe - Reprappers
Seems to me, the register got overwritten by a FW-routine. You have to find a different pin for Y_CS. Preferably ALL Y-pin assignments should be in the same register, but we don't know, since MKS is closed source...by o_lampe - Stepper Motors, Servo Motors, DC Motors
We've dicussed a method in a thread about 'exact constraint' and I made a short video, how the dual roller trick helps against racking. IMHO you could live with a single ballscrew and a cantilevered bed with that gimmick at both sides of the bed. Videoby o_lampe - CoreXY Machines
I've seem some very nice sand tables with RGB-LED's all around. A bit too bright for my liking, but a stunning difference to 'bright white'_only LED strips.by o_lampe - CoreXY Machines
Right, I missed that. It seems the Y-driver didn't communicate over SPI and hasn't received it's setup. This could be related to the different register, but I'm no expert.by o_lampe - Stepper Motors, Servo Motors, DC Motors
Can you please try something for me? Center the effector first. When you roll the magnetic rods between thumb and finger, do they all give you the same friction? It's important to pair up the rods until they give you the same feedback. The reason might be differencies between the Delrin sleeves. Some of my Mag arms seem to make contact between magnet and ball stud. The cup in the Delrin is too dby o_lampe - Delta Machines
Quoteprot0typ1cal Robot arms would be best suited to 3d printing a single object with multiple heads simutaneously, as a multi-head gantry system would get in its own way far too often to be of any real benefit. The slicer would be the biggest hurdle, that and getting some robot arms with enough precision to be worth even trying. Though I've seen videos of such a beast with two robots, can't findby o_lampe - CoreXY Machines

QuoteWhere is this regulator located (RAMPS 1.4 or LCD-unit)? QuoteAtmegas 5V onboard regulator Does that answer your question? The LCD is fed by the onboard regulator and some graphic LCDs are known to draw to much current. Some older SD-cards also have this problem.by o_lampe - Prusa i3 and variants
Sometimes I feel the tickling sensation too, when I touch the frame of my printers. The wall sockets in Germany aren't polarized, so we never know if Line and Neutral are connected the right way or crossed over. ( Doesn't seem to matter, tho ) Anyway, when I pull the wall plug of the Meanwell LED-PSU and put it in the other way round, the tickling is gone.by o_lampe - General
I read about people, who even milled the faces of their T-slot extrusion to have a straight base for mounting linear rails. If there's any unevenness on the faces, why bother milling the ends strait but leave the faces untouched? ( like many people do )by o_lampe - Extruded Aluminum Frames
