| If we want to print in ABS, heated table need |
There are instructions on how to do this on the official website of Spain BQ, but are outdated and only explain how to do it in version 1.4.2 , which differs substantially from the latest firmware more refined versions , such as 2.3.1 or 2.4.0 ( do not not try it with 2.4.0, it gives compilation error at the very beginning).
Well, in short, I will show how to compile the firmware to serve you for these and subsequent versions , with optional hot bed activated and working properly. But first, I show how I've ridden (and there tutos on youtube so I save this part - The guy in this video , although physical and clothing clavadito me, not me lol).
A clause ... is a company of the stature of BQ should have precompiled firmwares with different options , and let the user choose (even versions with height sensors for self - calibration table), it is outrageous that a user who does not have know anything about compilers, have to eat the head ... even though deep down that is when you ride a printer that whole piece yourself ... but it is a trifle compile and save many headaches (there are several threads forums questions about this topic).
Before anything else, apart from the table, cables and thermistor, to feed the table need a power supply of at least 12V 8A ( best of 11 or more); the more heat amps before the table and more easily keep you warm. The most economical and reliable is to use an old power source ATW at least 300W, by looking at the indicating amperes for connection + 12V, are durable and well refrigerated fan:
