Improved PCB Mill

thingiverse

These are the parts needed to take a cheap DIY PCB Mill Kit and make it more reliable without having to fight with getting it calibrated properly. It also allows much more cutting space with the same basic hardware as the original kit. You will need to print 2 of the following parts, and 1 of everything else: <ul> <li>flat_corner_bracket.stl</li> <li>side_bracket_current58_6625x3x4.stl</li> <li>stepper_motor_spacer.stl</li> <li>vertical_support.stl</li> <li>vertical_bracket.stl</li> <li>x_carriage_lead_nut_bracket_cover.stl</li> </ul> Optional Parts: <ul> <li><a href="https://www.thingiverse.com/thing:4220032">PCB Clamp</a></li> <li><a href="https://www.thingiverse.com/thing:4220094">Woodpecker GRBL Board Case version 2.8</a></li> or <li><a href="https://www.thingiverse.com/thing:4220161">Woodpecker GRBL Board Case version 3.2a</a></li> </ul> Most of the hardware from the kits can be reused. Here is a list of what is in this particular machine if you want to either build it from scratch, or if you want to compare what was in your kit to see what parts you need extra. The wiring harnesses are optional, and these models don't include the PCB Clamp, and Driver Board Case. <table class="waffle" cellspacing="0" cellpadding="0"><thead><tr><th class="row-header freezebar-origin-ltr"></th><th id="699678090C0" style="width:100px" class="column-headers-background">A</th><th id="699678090C1" style="width:100px" class="column-headers-background">B</th></tr></thead><tbody><tr style='height:19px;'><th id="699678090R0" style="height: 19px;" class="row-headers-background"><div class="row-header-wrapper" style="line-height: 19px;">1</div></th><td class="s0">Hardware</td><td class="s1 softmerge"><div class="softmerge-inner" style="width: 198px;
