![]() In the above sequence i just took out the heating. Wait for all used extruders to reach temperature In CuraEngine settings i have checked the option Enable retraction and in the Retraction distance field i entered 2 mm. I use the same SW with some modifications. How did you get the pen to lift? Or do you use custom SW?ĭon't forget a heatsink on the transistor. Or change the plastic from PLA to something more soft. I believe to be able to print directly on the cooper board you need to give it quite a good polish. For this o plan to replace them in the far future with industrial PT100 sensor. I also experienced that the thermistor from these printers go broke quick. Regarding the PLA i observed the same thing, color does give different adhesion behavior that can be compensated with +- 5'c adjustment of bed temperature. Probably i need to build an other machine since any mistake with that kind of tool would harm the heated bed. I need to get a biax small enough and with enough rpm to engrave the cooper board. I can buy new Fecl solution but i think it's not enough concentrated, or we get third order products (we had a very strong chemistry industry before starting with imports ). Now i'm thinking to move a step further because unfortunately my FeCl solution is saturated with cooper so the board needs some scratching after. I meant that i use the same printer for making things from plastic and the same printer to plot PCB board. I use a non expensive 0.4 mm permanent marker. I wonder if the colour makes any difference?īut I would really like to see a pic of a finished board, if it is not too much trouble for you. I never had any problems with one particular brand of filament, when I borrowed someone else's machine. Very clever.Īnd when you create the file you also remove any raft or brim.ĭid you have any PLA adhesion problems? This is one of the biggest problems I have, and I feel sure that my PLA will have difficulty sticking to copper without Pritt-stick. ![]() I thought you were using a pen, but now I see you are using PLA as the resist. ![]() Admin wrote:Thank you for the information. ![]()
