Hey there!
This morning I started tuning my profile in Cura. As base I used a normal Ender 3 profile.
After that, I made temp- and retract-towers.
I used PLA from Sunlu. As you can see, about 180°C is the sweet spot, which relatively surely tells, that the thermistor isn´t tuned correctly, but thats not the point in this post :D
In terms of retract, I made many tests. I tested the distance, the speed and so on and so forth.
The sweet spot (at 180°C) is:
Feel free to add your settings to the list!
Cheers & Happy printing

Sounds quite okay tbh! you should raise your Extruder current. this is set to 340 by default which is way to low. You can do this with Gcode (example is with 600mA which works fine):
M906 T0 E600
save to eeprom with M500
check value with M503
cheers mate and have fun with your printer! Would love to see a spreadsheet with the correct thermistor values and resistance, if you ever plan to create something :D
I have received the printer and I have build it. My home thermocouple measured the hotend between 217 and 213°C when it was set to 220 and left for 15 minutes.
My first print failed though because the steppers are skipping I think. I'll post the picture in the first prints post
My printer will be released from customs limbo somewhere next week. I have a high accuracy k-type thermocouple. I'll test the hotend temperature for accuracy. I can probably also borrow a couple of high accuracy heat measuring things from my work to test the bed.
So far I am not too impressed with the quality of the prints I've seen. My (8 or 9 years old) ultimaker 2+ still does better. The example prints Makertech showed were impressive though. Which is why I joined the kickstarter.
I hope Makertech will release a profile sometime soon as well as the DSH firmware and guide. They said they would release it this week but I don't trust that anymore....Too many broken promises.
