Oh and the process I used was draw the square in onshape, export it as a dxf, open that file in estlcam. Then in estlcam I picked outside and in tool path properties I set tool path depth to 0 and start level to 0 and exported the NC file. Then I opened that in repetier and saved the gcode file to sd. I also tried sending it via usb.
I tried some other files and it seems like it starts where I want on X and Y but Z lifts up a couple inches before it starts and doesn’t go back down. I did try putting in .5mm for the depth and I think it forces you to have something anyway.
[quote]What do you do in order to get the pen to start position?
I’ve not seen that behavior unless I had used manual control in repetier to move the z unit around and then it does exactly what you describe…
Perhaps also post the gcode you are using…[/quote]
That is exactly what I was doing… I moved it to the start by hand and it worked as expected. I was trying to plot the vicious1 logo and I didn’t have grid on in estlcam so I didn’t realize the size and it printed about the size of a dime
It didn’t seem to be putting the plot on the page where I thought it should so I went back to the 200mmx200mm square. I figured out it plots the square exactly twice the size it should be so that was making it hard to figure out where it was going to put it. I must have missed a step somewhere in the software part.
After the 4 year old goes to bed maybe I will be able to figure it out. I must just have the steps set wrong.
Changed my X,Y,Z steps to the values from the prusa calculator and now it is plotting the right size and I can figure out where it’s going to put the thing on the paper yay! Maybe one of you guys could tell me if I should do anything with the acceleration and feed rates? I have not had to mess with those in my 3D printing experience. I think I may need to change something one the Z it’s making funny noises now it didn’t with the wrong steps/mm.
Now I need to get this thing in the garage and get it all leveled and stuff.
I have 100,100,2267.72,100 for steps I left the acceleration and feed at what you had. I just used the numbers from the prusa calculator and it makes sense since they are half of what was in there for 1/32 micro stepping.
The Z still ran fine it just sounds different but maybe I need to adjust the driver current or something is rubbing. X AND Y are better. With the wrong steps in there if I told it to move 50mm in one shot the motors would lock and now they run good.
My 200x200 square was perfect size and even square.
