[Solved] Surface Quality Issue with E3D Cyclops
Re: [Solved] Surface Quality Issue with E3D Cyclops
Neither of them seems to have any slop. If I rotate either one of them, I can feel the transmission turning. If backlash causes a problem, it's probably hidden by your slicer doing loops from the inside to the outside.

Yeah, it's annoying knowing there is backlash... I'll see how much it affects anything after some more extensive testing. Thanks for the input.

Re: [Solved] Surface Quality Issue with E3D Cyclops
Printing the dragon thing has failed over and over again. At some point, KISSlicer commands the printer to print with the wrong filament and shut off the heater. It's not at the first tool change, either. It gets through a bunch of tool changes, and then suddenly it just screws up like this.
It makes no sense to me.

Re: [Solved] Surface Quality Issue with E3D Cyclops
Hey 626Pilot,
My guess is that KISSlicer is generating gcode to take the inactive extruder+hotend to standby temp, and after about 4 layers it doesn't have enough heat left to extrude after it keeps cycling between standby and print temps?
With the Cyclops, all that gcode stuff needs to be commented out of the appropriate tabs in KISSlicer.
If you're using v1.5 beta 2.20, look on the Printer G-Code tab, and comment out/remove everything in the following tabs:
- Select New Ext & Warm
- Warm Same Ext
- Cool Same Ext
- Cool and Reture Old Ext
Probably kinda hacky, but it will definitely work.
Don't touch Prefix (I think) you want your gcode to verify print temps before starting, and make sure you either turn off your hotend or take it to standby in the Postfix tab.

Re: [Solved] Surface Quality Issue with E3D Cyclops
Thanks for the advice. I commented all that stuff out (except T<EXT+n>) but it's still doing exactly the same thing.

You aren't using repetier server are you? I had the same problem then gave up on it626Pilot wrote:Printing the dragon thing has failed over and over again.

No, I'm running straight off the SD card.

I think you'll find the issue is with repetier firmware, not KissSlicer.626Pilot wrote:Printing the dragon thing has failed over and over again.

I saw exactly that when I had a none zero offset in the firmware settings for the nozzle, it would just occasional ignore the swap command. I moved the offsets into the Slicer settings instead and the issue went away. There was a supposed fix in later firmware, but I tried pulling that version and had the same issues.

I tried printing directly from Rep Host so that I could see which layer it was on when it failed, but RH decided to screw up the g-code and it stopped tool-changing entirely. (Which I find crazy, why would it mess with the G-code instead of just sending it?)

Re: [Solved] Surface Quality Issue with E3D Cyclops
Hmm... Maybe it was a repetier host issue then.
Makes me wonder what it's doing, all it's supposed to do is strip comments and add a line number and checksum.

Re: [Solved] Surface Quality Issue with E3D Cyclops
It's printing now and seems to have made it higher than it ever has before. This is what I put into Select New Ext & Warm:
The other extruder change tabs are all commented out.
In theory, it could be that something in Smoothie is getting confused when the toolchange (T0/T1) code is sent that causes it to forget what temperature it's supposed to be at. I suppose it could also be that I pasted something in there that confused the parser (maybe it had \r at the end of the line and Smoothie expects to see \n or \r\n). "Forgetting" the temperature and no longer selecting the right tool sounds a lot like a parser error to me.
Code: Select all
; Select new extruder
T<EXT+n>
; Warm it up (don't wait)
M104 S<TEMP>

To prime the extruder on color changes, I used "Wall (all layers)". The short wall option didn't work as well - lead to the small layers on top getting too gooey.
There is more stringing than I saw before, probably because my initial test prints were with PLA and HIPS. I guess HIPS doesn't have the same thermal expansion? Maybe? The 1st model was printed with a wipe setting of 10mm, the second with 5mm. I think that helped a lot.
The weird thing is that even though I'm having it do a full-length wall, there's still substantial color bleeding. It makes the output model look kind of weird. Is there anything I can do to reduce that effect?
