anet a8

[manotroll]

has support for anet a8 do you have support for automatic leveling? Do you have temperature protection?

This thread was a ton of help. Here is what my config file looks like right now. Shes printing great, 200mm/s no problem. Biggest difference from above was the z step distance. Also the bootloader info was great, no bootloader on mine to start. You can easily flash a bootloader with the LCD cable on the Anet, an arduno, some spare wire, and google!

Does anyone know how to make the bed heat before the extruder when the print button is pressed on octoprint?

[diekaines]

@nickcaruso do you have stock anet a8 ? Really interested in trying that config you pasted above

[rewolff]

Nick: bed/extruder heating is done in GCODE. in your slicer, there is usually something called start gcode that does things like home and warmup. I just looked. In slic3r that I use, apparently the things slic3r thinks it needs are not in the startup gcode section.

@kotfarepra I believe so. When I purchased it I don't recall the name... it was an eBay china type purchase. But I have been using anet a8 support and everything seems to be the stock anet. I would use the config file. Home your Z, and make a 100mm move and measure to check for accuracy.

MrWu-at-msv you saved my azz, i couldnt connect till i added the baud rate under mcu
