even i am suspecting the sd card reader . i am printing directly via the usb right now to check it if that is the cause.. .. I even suspected the ssr on the headed bed as that is very close to the steppers but i ruled that out by printing on a cold bed.

Delta Machines
hi,
I have a 3dr delta working fro the last 6 months. Most of the time the printer works perfectly. But with some files the printer just freezes mid print and resets itself. Those particular files fail at a random point no matter how many times i try printing them.
I am using marlin and slic3r.
Any clues if it is a hardware or software bug?
thanks

use springs on the arms or you will not be able to eliminate the play .

The 5 wire stepper cannot be used. The 6 wire can be used by using the first 4 'wires or finding the wires which make the coil pairs.

i have a mendelmax with different motor on all axis.. All i did was to tune the stepsticks differently for different motors ( to make them cool and quiet and still have enough torque ) .. The printer has been running just fine for last 1 .5 years

@mbttger
i dont see mixing happening in your extruder , just color change in one hotend .So how is it a multicolor hotend?

@vreihen
the board files are missing. Just the schematic is not enough to be open source!!!

There is no firmware for core xz just a gcode post processor . This was not meant to be a new printer but a retrofit for the prusa i2 .

Yes i mean check in luggage and asking such questions to a airlines raises suspision. Guess then i will just have to try. Worst case gift it to the customs or whoever objects it then .

i searched and could find a answer to this question. I want to take a disassembled mendelmax on a international flight in my luggage. Does it cause any trouble ( metal detectors / customs ) etc ? any experiences?

i dont think the force of the magnet would be enough to mix the semisolid plastic. It requires quite some force.

y do want to do that? you will need 2 hotends to do that... ( the sleve in the j-head is a bad technique ) ..

Anybody with experience of using the drv8825 outside of a ramps/reprap setup? I have a stepper driver board to drive micro steppers running at 6v . The stepstick work seamlessly but i had some drv8825 boards and tried them and they wont work. I checked the datasheet and it said the operating voltage of the drv8825 is 8.5-25v and of the stepstick is 8-25v . The only difference is that the drv8825

Most cheap kits have these issues due to plain carelessness/ignorance... I bought a Prusa i2 kit 2 years back and the seller didnt even know how the hot end actually works.. I ended up changing most of the parts in the kit.
Buy from reliable sources ..

i have seen some corexy builds .I see some use toothed idlers and some sure plain bearing as idlers. Which is better? Is it necessary to use toothed idlers?

another question is what information is enough to call a electronics board to be called open source . Some boards ( RADDS ) just share their schematic as a PDF and call themselves open source.. Aren't source files/gerber files necessary to call yourself open source?

Well was planning on making a radds based board as till now for both my printers i have made everthing inclyding the pcbs so was not keen on buying a radds board as there is no fun in that. Anyways i will layout my own board and call it something else.
Sorry about the misconception of open source... i had

I cant seem to find the pcb files for RADDS .. I thought it was open source according to the wiki....

point noted .. posted on thingiverse....if you want i can mail you the rhino/stp file if you want to take a look at the 3d... And the 'sales' is just because i have spare pcbs and motors... not a large scale one .
