Found the cause! Limit switch Was disconnected at terminal. But it was weird because instead of moving towards the limit switch the carriage was moving in opposite direction. Also it appeared that a crash cauded the problem, but actually the open circuit must have been what caused the crash.by dolon - Extruded Aluminum Frames
This i3 style printer has been working well for several months. Today after a crash it does not home the X-axis properly and heads off in opposite direction. What would cause this behaviour? Any suggestion on how to fix this. Thanksby dolon - Extruded Aluminum Frames
Thanks for your reply. I only have a 40mm fixed fan. I think my Ramp controller may have a socket for another fan, but I would have to create a mounting for it. I have modelled a shroud that surrounds the heatsink, so will give that a try first.by dolon - General
I am seeing all types of fan shrouds, but not sure if any of them would suit an i3 type clone with a single fan and a Bowden Extruder. The fan is mounted on the plate that holds the hot end. I would like to make my own, but need some guidance on what it should achieve. As I see it the aim is to cool the fins while keeping the air away from the nozzle. However, I'm not sure about cooling the printby dolon - General
This has been the problem. It seemed to move up 15mm, every time it was started. I think firmware was causing the weird moves. It is the Auto Level version and I was trying to rely on a Z limit switch. But I think I have got it all working now. Printed my first part and it went well. (The part is actually a bracket to hold the sensor as the supplied acrylic needed much modification.) I changedby dolon - Extruded Aluminum Frames
Finally assembled my Flsun i3 Kit and after lot of false ends have got Repetier Host connecting to it. Also corrected problem with a blank controller screen and Z axis going the wrong way. Both were the result of wrong firmware. The supplier emailed a new version of Marlin. The problem now is that at the start of a print the Z axis moves 15mm above the zero limit switch and begins printing in miby dolon - Extruded Aluminum Frames
QuoteDust Home is front left of the bed on most machines (except deltas), some 'really weird' people also use back right, its valid, but very confusing. min/max depends on machine configuration. For a I3 type machine its the following. X is left/right. Min is left, Max is right, X- moves head left, X+ moves head right. Y is front/back, Since the bed moves vs the head. Min is at back, Max isby dolon - Prusa i3 and variants
Quotelkcl well, you can always leave the belts off the x and y, then try running "Home" on X and Y in turn, and manually press the limit switch. . Yeah, just watched YouTube video on an Anet A8 assembly. The guy does an Electronics dry run with all the devices plugged into the motherboard. I need to make sure the motors are spinning correctly, to suit the Y- axis belt assembly. Thanks, for theby dolon - Extruded Aluminum Frames
How did I get here? I started with a lot online window shopping and warnings of 'you get what you pay for' etc, but decided that I would do my research properly. Even began a Comparative spreadsheet and quickly realised that there was not much separating the budget units. Decided to then just look at Sellers with the most orders and plenty of feedback. It then appeared to me that Flsun were eageby dolon - Extruded Aluminum Frames
