    How long were the 1/4 x 20 bolts you guys used? I'll be making a hardware run within the next few days. Trying to make a list and one trip if possible. So far I have the pulley grub srew swap and these stepper bolts. Now to find the tap set I placed somewhere in the garage quite some time ago.

    I forget. I think i just used what I had on hand at the time.... just measure the stepper mounting plate thickness, and add the 1/4" for the MDF and some extra for a washer, plus a little sticking out.

    3/4" are fine but 2 will need to be 1 1/2" on the X axis stepper. I bought a box full of 1" long bolts because the box was cheaper than just a few.

    Not so much as a build tip, but, on finishing my P3, I made stupid my final step. Forgot to lift the Z gantry up a bit higher and jammed the pressure roller into it as I was raising it to the up position. This sent the top bearing through the MDF and damaging the Y7 piece. I'll order a new one but after some thinking and digging through what I had on hand, I found some roof truss support plates left over from a recent fence project. Whipped out the dremel and cut off a chunk of it. Cleaned the burrs and found a few matching machine type screws. Add washers and made a retention plate to secure the bearing. So far its working like a charm but I haven't tried loading it yet.

    I know I wont be the last guy to rip up his Z gantry. Necessity, Mother of improvise, adapt and overcome. Attached files [​IMG]

    Yep, Been there, done that too. Am trying to get into the habit of raising the gantry when done cutting now. I like this mod. I will be doing it to mine as well. Thanks for the tip.

    +1 on tapping the stepper motors with 1/4 20 threads. I'm in the middle of building #42 and wanted easier mounting for when I decide to go back and apply shellac for moisture proofing the MDF.

    I had put one side of the belt in its seat and put the cover on. I then started the screw, but just started. I lifted a bit the cover and shoved the other side of the belt in until it was seating well. I clamped with my thumb the cover down and now I could screw the screw tight. :dance3:

    I didn't tap my steppers with 1/4". I thought it would make the walls of the hole to thin. I wanted to do it with #12/32 screws but they are hard to get. 6mm, on the other hand, are a dime a dozen so that what I ended up using. You don't even have to drill the hole for the tap. :doubleup:

    I went into the ruby script that makes the phlatscript and changed the line, at the bottom, where it says 'G0 Z0' to 'G0 Z2'. Now it goes at the end of the job to the top, or almost to the top. Since I have the limit switches it makes no difference how thick the material. that I cut, is. It will only go maximum as high as the limit switch.
