owen

No. It is a theoretically better to go in multiples of 0.001875mm Zlayers Thread pitch 3 mm microsteps per step 8 steps per revolution 200 micro steps per revolution 1600 mm per microstep 0.001875 0.001875 divides nicely into 0.03 so for ease you can go multiples of 0.03 but I'm not sure how much difference it makes. 0.03,0.06,0.09,0.12,0.15,0.18,0.21 I've been mainly going for 0.12 myself and would mainly just go for 0.06 for a finer print. Finer will always be better though down to a point. Under a certain level the print gets whispy and you can't see the layers and creates more warping.

I've been using 5% for support setting and making my design to keep support away from a thin vertical wall that it was sticking too firmly too. The overhang is zero degrees 10mm X 10mm corner, so not a bridge and it's has been coming out perfect (printed 6 of the object). It has been very easy to peel away and the surface is almost as good as the top surface.

Beta 13.06 http://software.ultimaker.com/Cura_closed_beta/

Not sure if this will help. http://www.thingiverse.com/thing:31581

Latest Cura has different speed for perimeter and Fill. It doesn't matter if you use the Ulticontroller or not.

It looks like the Z seam, which happens on the Z move. It seems less in latest Cura and is adjustable in KISSlicer.

What's your layer height and temperature Lars. Maybe you just can't extrude that much volume at that speed, height and temperature.

Welcome to the forum Marco. I hope your UM speeds through customs.

Petty good result Olivier

Hi Dalia I think it would be prohibitive for CGTrader to print any models out but the designers should be printing them out and putting photos with there designs as well as the printer used, layer height, software used support used, heat bed and any other relevant settings. Maybe also a feedback from purchasers whether they printed it successfully or not which gave a printability rating to the model.

That's what I don't want.

Yep, I'm looking out for filament that has a higher Glass Temperature the PLA but isn't ABS due to the hot car problem.

Thanks for the info. Do you know the Glass Temperature for PET?

Yep, That's a good idea Olivier. It should work.

Right click on your part and click multiply. You can move and rotate the parts separately now and Cura slices one after the other

That looks good Olivier Good luck

Yep, definitely use your existing GCode It looks like Cura doesn't zero out the E value at each line so here is how you zero out E (Extrusion distance) Example from my GCode ;LAYER:47 G1 F2400 E467.40886 G0 F9000 X119.80 Y102.90 Z5.94 ;TYPE:WALL-INNER G1 F2400 E471.90886 G1 F2100 X119.80 Y102.99 E471.90955 The Z height is 5.94 so after you home you will want to move to this height without X or Y movement G1 Z5.94 F2400 ; Go slower by adjusting F down if you want to Prime/Wipe nozzle during this move G92 E471.90886 ; Make the UM think it's E value is currently already up to this amount so it doesn't extrude or retract at the start from here go with the lines from Layer 47 on. ;LAYER:47 Just a comment (leave or remove it) G1 F2400 E467.40886 A retraction from previous layer (remove this line) Keep all lines from here till end G0 F9000 X119.80 Y102.90 Z5.94 Moves to the first spot (No extrusion and Z is already there) ;TYPE:WALL-INNER G1 F2400 E471.90886 E is already here so it shouldn't extrude here G1 F2100 X119.80 Y102.99 E471.90955 This will be the first printing move

Hi In your GCode You need to make sure your [*]Nozzle is heated up and primed M109 S<Temperature>[*]Fan on M106 [*]Nozzle Homed G28 If you are using Cura the Start Code will have comments and you should be able to make sense of what to leave at the start or show us your start code back here and the first line you want to print Next to Insert after the start code is GCode to move the platform straight down so that the Nozzle doesn't knock into your model. G1 Z99 F250 ;If the height of your first required layer is 99mm, F250 sets a steady speed Next you need to Zero your extruder to that of the first required line G92 E1234.5 ; example number though I think Cura may zero it out at each line anyway From here you carry on with your code I think I have that right. Like I said if you unsure said your start GCode here and the first few lines of your desired starting layer G0 or G1 = Move Followed by combinations of Z, X, Y and E for what to move and F for speed of the movement. If any Letter isn't there it remains as it was.

Maybe a tick box that says 'slice now'. That way we could leave it ticked for the smaller jobs so as to maintain the current behavior. I like it as is, as you can see print time and material use get updated as you change settings.

Hi Sam Look in you end GCode for Cura It might already have code like this (Need to view full settings) G91 ;relative positioning G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure G1 Z+0.5 E-5 X-20 Y-20 F{travel_speed} ;move Z up a bit and retract filament even more Just add a higher value to Z or add a line after G1 Z20 ; Move the platform down another 20mm

Hi Paul You can put in some code yourself in the meantime to achieve what you want. M220:set speed factor override percentage Example: M220 S80 S<factor in percent>- set speed factor override percentage

If your hardware seems OK, maybe look into the possibility of the head bumping into raised plastic.

OK thanks for that. Didn't realize that about layer thickness making a difference. 120mm is a fair way.

Hi Nick Could you do a system restore back to before it started?

How far can it bridge generally Daid?
