I have find this video, seems promising
NON PLANAR LAYERS](https://youtu.be/km1lvuva5mI)
think i have find it...
After several tests, I saw that the problem was always similar, it did not matter the material, the layer height, the speed of printing ... after 1 or 2 layers, jamming occurred, and loss of steps of the heater, which another part is a double gear striker, and the voltage was raised to 800 mA in config.g.
Seeing the stuck filament, it looked like the tip formed a ball, and the distance coincided, approximately where the nozzle began.
At this point I have to say that I use a Prometheus v2 hotend ... seeing the documentation of this, I saw an error when I mount it ... and I did not put Thermal Silicone on the nozzle, so I put thermal silicone and gave it more distance the Heat Block to the Heat Skin. Before I had 2 mm, and I have put two nuts, in addition to 2 mm. In total about 6 mm, which forced me to modify the config.g, and adjust the loss of height effect
With this I tried to separate the source of heat, Heat Block, Heat Skin, and try to get the heat, did not reach the Heat Skin, and did not melt the material, this along with the silicone ends, it seems that it is working.
I have two impressions, with ABS, and for now, everything is correct, I still need to try PETG, which uses a higher temperature ...
I share my evidence here, in case you can serve someone ...
The truth is that it would have had more influence, if the silicone, or separate the Heat Block from the Heat Skin ...

Before you install your heater cartridge, you should double check that you both purchased and received the correct voltage cartridge. Cartridges are laser etched with their voltage, but all it is worth double-checking anyway. This process is less annoying than putting out a house fire. If you have a 12v30w heater cartridge, your multimeter should read 4.8Ω If you have a 24v30w heater cartridge, your multimeter should read 19.2Ω Your cartridges resistance may deviate slightly from these numbers, which is fine. We're mostly interested in verifying which cartridge type you have. If you have a 12v 40w heater cartridge your multimeter should read 3.6Ω If you have a 24v 40w heater cartridge your multimeter should read 14.4Ω
It will be ebook avaliable?
some idea where start?
Can someone post your config?
In this moment have this:
Short Bowden, aprox 20 cms.
Pressure in advance: M572 D0 S0.1
When i try to print various objects, i have clogs in first 20 layers, aprox
I am having some problems with PETG and retractions, when I try to Print some objects in the same bed... In first layers I have clogs... However, if I print one or two copies of the same model, I do print it...
I think that can be an issue of retractions... If I fine tuning pressure in advance can quit or almost reduce retractions?
