Sounds like Atmegas 5V onboard regulator gave up. You can use a 1A USB phone charger, if you don't want to connect it to your PC permanently.by o_lampe - Prusa i3 and variants
The reason I asked this, was to find an excuse to build a new cable driven printer. I though of extruding ketchup, mayonaise, mostard a.s.o. simultaneously. Therefor a tool changing system would be less useful.by o_lampe - CoreXY Machines
QuoteJoergS5 Quotethe_digital_dentist Belts normally load the motor shaft on one side. I don't know why, but people who play with cables seem obsessed with the motor shaft loading. The reason for this is for me, that the stepper inside has ball bearings and a load on one side will disturb the function of the stepper. Like a direct stepper - shaft connection which destroys the stepper (the reasoby o_lampe - Mechanics
QuoteDiggrr 4 is the most I've seen, I gather it's a limit as to how many drivers you can hang off of a board as well as kinematics getting complicated, being on the same plane and all. Tool changing looks to be more promising, if someone were to build a multiplexer board--a one driver board that switches what tool (extruder motor) it's running via g-code. Then you could fill the back wall of a pby o_lampe - CoreXY Machines

QuoteJoergS5 The wires must be forced to a specific angle between corner and the middle. In your case the wires force each other into this angle, but you have friction and maybe abrasion. If I'd use thicker washers to set the vertical offset, the wires wouldn't rub against each other. Bending the screws to angle the pulleys is not neccessary and would be difficult to assemble when using a closedby o_lampe - Mechanics
Do you use TMC2130 for the extruder too? IMHO they don't have enough grunt to extrude fast enough. Your e-steps of '105' tell me, there is no gear either...by o_lampe - Reprappers
We've seen dual heads on one X-gantry and also dual X-gantries on one frame. Is '4' the max. number of 'independent' printheads? Is it restricted because the belt routing gets messy? Would it be easier with cable drive? The cables wouldn't need so much vertical space and are easier to cross. Will we ever see a printer with 4 heads working simultaneously?by o_lampe - CoreXY Machines
Quoteruyvieira That would be very useful as a laser cutter for textiles Usually they use a bandsaw to cut a huge pile of textiles at once. I don't think a laser can cut more than one layer without melting them together. But a CNC laser, based on that CoreXY frame is a winner for sure.

The soft silicone rubber didn't make it. It didn't slip at medium tension , but the cable tightened so much, that the pulley diameter changed. The cable almost disappeared in the silicone. I have to repeat the test with brake hose or fuel hose. ( real rubber ) If that won't work, I think of an aluminum pulley with sandblasted surface for more grip.by o_lampe - Mechanics
What Arnold said, or a severe shortcut on the Ramps/Atmega board. Did you check the solder job on both boards?by o_lampe - Printing
There were several new threads regarding cable drive and some of them stopped tinkering and went back to belt drive. I still think, the new found solutions deserve to be collected here for later reference. Here's my approach of a non-fixed cable drive that doesn't allow the cable to walk up/down. It's a spinoff of polygonhells design I'd like to honour here. The Digital Dentist took it and addedby o_lampe - Mechanics
What exactly do you mean with 'stepstick' ? IMHO the real stepsticks are so outdated, noone uses them anymore. If you meant ' stepper driver' in general, there are several different versions out there. They can differ a lot regarding microstepping. If you replaced an 1/128 driver with an 1/16 driver, it would try to run much faster and got 'flooded' with step-pulses it can't compute fast enough.by o_lampe - General
You could remove the upper bearing of the leadscrews first, before adding a third. It was this bearing that lead me to the (mis-) conclusion of no extra z-guides.by o_lampe - CoreXY Machines
In the prusa edition it's there:by o_lampe - Slic3r
Using the leadscrews as Z-guides too is a bit unusual. The print doesn't show any signs of wobble yet, but maybe after some hours of printing?by o_lampe - CoreXY Machines

A few people experimented with rotating beds, but AFAIK there is no specific mode in a slicer yet. Usually the radius is Z, the cylinder-height is X and the Y-axis is configured to rotate CW and CCW. ( No vase mode ) Maybe you can get away with defining an 'infinite' length for Y-axis. 32bit controllers are able to deal with several 1000m. ( was it 9km?)by o_lampe - Slic3r
12V 20A is enough for a printer with unheated bed. Can you provide a picture of the hotend assembly? There should be a gap between heater block and heatsink. Otherwise the heatsink will suck up all the energy.by o_lampe - General
Some earlier slic3r version weren't able to deal with changing the nozzle diameter in the setup. You had to start a new printer profile. They seem to have found the bug ( at least in the Prusa Edition branch ) but it wouldn't hurt to start from a new profile and see if it works better. Some of the features seem to be taylor made for 0.4mm nozzles. I'd try to use 0.8mm extrusion width and 0.5mm lby o_lampe - Printing
Quote(I'm actually kind of excited about this as a possibility.) Has anyone tried to port DuetWebControl to a RasPi? That's the more elegant way to set communication IMHO. Integrating the RasPi-camera would be the icing, but common USB-cams will do too, I guess.by o_lampe - Duet
You can send M119 or M114 to get the endstop status or position reported. That would clear up any mis-configuration about homing. A common mistake is to set homing direction or position after homing wrong. The printer then thinks it's somewhere els and doesn't want to move out of bounds.by o_lampe - Prusa i3 and variants
Maybe the MOSFET on the MKS board doesn't switch ON fully? It's a common problem on Ramps/Atmega-based controllers, when the onboard voltage regulator doesn't supply 5V, but only 4.5-ish. The Fet sure gets very hot then...by o_lampe - General
It's probably the overtemp protection in firmware. There often is a safety margin that kicks in 5-10° below max. tempby o_lampe - General
If you want to try something new, mix belt and cable. Belt only where needed to fight slip and cable for the rest. ( ~50:50 ). I did that on my Kossel XL Delta and it reduced ringing a lot.by o_lampe - CoreXY Machines
There is a grid in slicer you can use for orientation. But there is also a 'move' section in the plater: Select the part you want to move and open the 'settings' dialog. Now you can use XYZ sliders to move the part in a more defined way than just ' drag and drop' with the mouse.by o_lampe - Slic3r
