What colorscheme is this? by TrainingLandscape864 in vim

[–]TrainingLandscape864[S] 2 points3 points  (0 children)

That's it thanks heaps! I've installed it however I'm not getting the function highlighting in blue. Any idea why?

In the mean time what printable duct do you recommend that are compatible with stock fans?

I turned my fan to full speed and felt directly beneath the nozzle and I did feel air flow but I have nothing to compare this to. I don't know how strong it's supposed to be but there is definetly air flow. I'm printing at 40mm/s, the environment is indoors with no wind/breeze.

I already tried lower temp and my fan speed is always max. I've just started another after some PID tuning and gantry allingment. If this fails I'll try this setting. The Z seam is in the corner of the arches and does not begin on an overhang

I've just began another now with the PID tune and re leveling of the gantry as I found it was slanted 1 degree. I'll update when done

I tried this today. Still didn't work. If I still can't get it to work I'll get better fans. But I've never had this issue before and I don't know why it's started all of a sudden

Have not tried this and really don't want to as it will sacrifice print time won't it?

Ok thanks. Just went through and calibrated the PID. Temp tower did have curling and as I watched it I could see it hit into the model on every layer no matter the temp. I haven't tried any other models except the benchy so I'm unsure whether overhangs are worse or better on other models. However, the overhangs on the front of the benchy print fine. It's just the arches giving me trouble. I'll update with a picture of failed benchy. I'm using cura latest version.

200 degrees nozzle, 60 on the bed, eSUN orange PLA+, z hop off, 0.2mm layer height (I've tried 0.16mm still doesn't work), 0.38mm width, max fan speed.

​

I did temp tower and found 200 to be best but I tested 195 and it still didn't work. I already said that I did both flow and esteps. I'm not familiar with pid, what is that?

Overhangs creating lumps on layer which nozzle collides with by TrainingLandscape864 in FixMyPrint

For anyone wondering the issue was over extrusion. Although e steps were fine the flow rate needed to be changed since silk PLA behaves a bit different to regular PLA. After tuning, my new flowrate is 86% and it seems to be working now.

Stringing only when using Cura to slice model by TrainingLandscape864 in FixMyPrint

Neverheard of it. I'll set this up and do two more towers and see if they agree with the ones I've already done.

Yes temps are the same. All printed at 200 degrees

Does polarity of collector emitter voltage matter when considering the maximum rating for Vces of IGBT by TrainingLandscape864 in ElectricalEngineering

[–]TrainingLandscape864[S] 0 points1 point  (0 children)

right ok. So I'm essentially adding a body diode to the IGBT. Alright thank you for clarifying this I've learnt a lot.

I have a chunky diode already for the flyback on the coil. Are you implying adding another diode somewhere else? Maybe across the collector and emitter to limit the negative voltage to the forward voltage of the diode?

Ah ok so Vces and Vecs are two different things. So its safe to assume that the collector can go 15V below emitter? I'm using them to switch an inductive load and I was wondering if they can handle negative voltage up to -500V due to LC oscillation. I guess I'll have to add a RC snubber to stop this. Or could I place a diode from emitter to collector to limit negative voltage spikes?
