    • RE: How to home (G28) midprint and resume?

      @lazy_mosquito
      Can you add a bracket to the printer frame (bed respectively) were you park&lock the effector before filament change?

      Thats an option i was also thinking about, but more complex to achieve compared to code.

      Thanks already for your answer.
      I would expect it behaves similarly to adding it directly in the code.

      But I will first try to invoke it via the pause and the resume macro and sees if it makes a difference instead of invoking it directly in the g-code.

      i just create the macro's and invoke them manually after the prints pauses?

      This would work in a normal situation, it works on my Prusa. But on the Prusa it is very easy to change the filament without moving the printhead, which is almost impossible with my delta printer.
      The problem is, that the printer will restore its position from the existing,moved, coordinates, but when the head is moved by replacing the filament, the printer has lost its absolute position and will go back to the wrong position, that's why I would like to home it first. In that way, I can reposition the head back in a known position and start from there.
      My printer has rods of 72 cm, which makes that any force you put on the arms easily overpowers the holding force of the steppermotors, specially with my extruder. It works very well but is a pain to load new filament.

    • How to home (G28) midprint and resume?

      I want to do a colorchange with my duet 0.85 in the middle of a print. I can pause at the right place, but because i have a rather big delta printer with a fidly filament change it is almost impossible to change my filament without moving the printhead. My solution was to insert a G28 command after the break in the g-code; so it would center it again before resuming print. but after the g28 command it homes indeed but stops and tells me the print is finished. Somebody another idea how i can rehome my head again after filament change in midprint?

    • RE: No Green Light blinking at Startup.

      I hae the same problem. no green led ad startup and no green led with tap.
      It used to work and i didn't change anything (except of dissasembling my printhead a lot of times to solve a printing problem) when i measure between VCC and gnd i get 0,65V instead of 3,3V. Any idea what the reason for this could be?

    • Clamp a direct extruder on top of the smart effector

      Hi,

      Would it be possible to clamp an extruder (flex3drive) directly on top of the smart effector?
      It would be fixed by the standard holes in the pcb, but it would be touching the topside of the pcb on the whole surface to give it more rigidity. Would this be problem for the sensor. At this moment there is a kind of isolating ring between the bolt and the pcb for fixing the heatsink, i would use the same material between the extruder and the pcb.

    • RE: Extruder keeps stuttering… out of ideas

      Found one of the problems: E3d delivered me three 1,75mm nozzles where i ordered 3mm nozzles. The fact that i didn't use any 1,75 mm nozzles before i didn't notice the difference, i thought it was normal to have a bigger melting room with a bigger diameter. Because i ordered now 1,75mm nozzles, i noticed they were the same as some of my previous nozzles.

      But because the supposed 3mm nozzles didn't work, i started modifying my heatsinks, I changed a direct drive to a bowden by adding a threaded clip on top of the direct drive heatsink. This didn't work out (ridge on the inside) so now i have two damaged heatsinks, and no working extruder. Also i just discovered that xl Bulldog extruders are delivered with too wide tubing. They deliver 6/4 mm for the 3mm filament and 5/3 mm for the 1,75mm filament, which makes the filament, specially for the 1,75mm filament blocking on the entrance of the heatsink.

    • RE: Extruder keeps stuttering… out of ideas

      It has to be something like that. It goes effortlessly until approximately the start of the heatbreak. So probably there is some kind of minimal obstruction there. but enough to block the filament. I will disassemble the extruder head again for the 300th time and check for some obstructions in the flow channel or tube or connection of both.

      thanks both for the advice.

      i post the follow up
