Yes, at second look the g2/3 commands not are very useful with this mcu (atmega2650).

I just open a issue on slic3r githup for ask they to add a "correction coefficient" for holes

Really interesting. In practice the error is made by slicer that no do a compensation on the mesh. IMO an little modification on slicer that scale up any circle or arch by a coefficient of they triangular face can correct the problem. In fact if i measure the circle the first inner perimeter is just ...

After a week of test i'm not been able to obtain a right dimension of my printed object. Usually the external dimensions are right or slightly smaller but every circle and hole are smaller just of 1 / 0.8mm There is not correlation with layer width and hole error; i also tried to switch my nozzle ...

So there is no way to modify the gcode?

When i uploaded the gcode repeater can't redownload it; it can only start the sd print.

The strange is this, pc can't read but rambo work

I tried to modify a old gcode uploaded through repeater to my sd but it look like unformatted/unreadable jam of symbol.

I used notepad, gedit, word and google doc for open it without success.

Any idea?

Unfortunately no. My original tube is too short. ( i cutted it :oops: ). So my printer can't reach the X tower. I'll attempt ask to my hardware store to find a similar tube.... but i know only one dimension for this type 2mm int. / 4 ext. Probably the material make difference. Edit: I'm feel so ...

PROBLEM DISCOVERED

I replaced the guide tube with another one of same internal diameter; re installing the old all work well;;;;;

This is a well mystery.... why this????

Thank Eaglez, tomorrow i'll try to put a fan (is midnight in Italy now), hoping to fix

Yes in fact i add a heatsink on all motor driver with a thermal pad to prevent overheat and made some hole on the bottom of the front panel. I also added 4 small heatsink on the motors ( 1 per side ). My doubt is: can the aluminium heatsink disturb the motor?? The extruder motor is the only one have ...

Hi all, today my printer have a strange problem. I try to extrude 20 mm of ABS at 100 mm/min and at 200°c but my eztruder motor do a back jump sometime; I checked the guide tube; the extruder and the wire on the rambo board but all seems good; Releasing the motor hold and turning the white gear the ...

Wow, i made a hot Topic :D I think that the best way to lock the thermistor is in fact the threaded capsule, this method is the only one can guarantee optimal thermal conduction and retention over time; also is easy to replace and made at home. An other question is a method to keep in place the ...

Hi all, i just starting to build my V2 but i can't find the Permatex Ultra Copper RTV in Italy. This silicone have particular thermal property or is like a Normal Hight temp silicone. I mean, is it particular thermo conductive? I have a Arexon Motorsil in my toolbox; usually i use it in my ...
