So I've trimmed it so the angle brackets are touching but not actually penetrating either the shelf with the corners cut away, or the front panel, and left the brackets at 4.4mm thick at which point those 3 artifacts disappear. It's also doing the horizontal holes surprisingly well so this one may be usable. The next rendered version if I have to print another, will be my 2nd with a PCD nozzle in the printer, but will be done in Atomic's carbon fiber black PETG and will have 5 ribs for re-enforcement. Might be fun. If I can tolerate the wait. This is intended to be printed shelf (face with clipped corners) face down. It will hold the 4th axis supplied with a 6040 gantry style milling machine, after it has been retrofitted with a 50/1 harmonic drive and one of the brand new 3 phase stepper/servo motors. Those are sweet. If anyone else buys that mill, expect to use your trash trailer for target practice to see if you can hit it with ALL the electronics, its all built by lowest bidder stuff and won't do the job. You also use up the spindle motor in 10 hours, so figure on a real motor and a vfd that takes orders from decent software. I will have, when this conversion is done, about $3800 in an $1150 mill. Its job will be to hold and rotate an 18" long 2x2 hard maple stick, while LinuxCNC is carving a 2" diameter, 2 start, 12mm pitch buttress thread to make the screw for a woodworking vise. This drive weighs about 15 lbs. If this PETG doesn't cold flow and sag that is. Many thanks for the advise showing me I need to be more precise. Thank you all. BAxisShelf5.stl

That stickup out of the side of the shelf does not exist here, in OpenSCAD, or a cura preview. The solid part of that brace only penetrates the skin of that shelf by about .2mm, So where is the stickout of a fraction of a mm I see in the top edge of your 1st shot, coming from? Call me puzzled. Thanks Gene1934

Greetings all; using the latest AppImage for linux to drive a BIQU BX printer, I've designed, in the latest OprnSCAD AppImage for linux, a shelf to be bolted to the rear of a 6040 mill, intended to support a B axis drive I've made. But I've now stopped the printer 4 times because the effects of 3 angular braces supporting this "shelf" are cutting the 10mm thick shelf into 5 pieces internally as soon as the infill starts. I have found I can make this artifact disappear if the angular brace is thinned enough there is no infill, its all wall. Is this a bug, or intentional? If its intentional, can you share the reason? What I've found, using the preview progress slider on the right, is pretty well stopped if I make the angular braces only 4.4mm thick effectively making them solid walls. If I make them 7mm thick, I get 5 pieces with a good floor on the bottom. 3mm up in the print, I can put a probe in the slots all the way to the bottom 4 or so layers. The attached pix shows what it should look like when finished. For some reason the left edge is clipped here and the green lines are the edge of the angular angular braces. View is of the bottom of the shelf, looking up at about a 40 degree angle. One side advantage is I now have a good drill and tap template from the last false start. Those bolt holes are identical for both panels.BAxisShelf.stl I'd post the OpenSCAD.scad file here. its only 88 lines of text, but its not acceptable to the forum software

Ultimaker-cura does not identify the printer associated with the "print via usb" until AFTER you have clicked on the "print via usb" button. So my BIQU HX gets gcode intended for a Prusa MK3S+ and vice versa. Linux multitasks at something like this very well, and since both printers are glacial speed usb-2 devices, there is no reason we can't start a job on printer A, clear the plate, select the other printers profile and load a job for printer B, slice/render it to THAT printers profile, AND select printer B to send the gcode to. Can this be addressed? When two or more printers are plugged in and detected, giving multiples of the "print via usb" targets in that selector, identify the printer in the multi-selector menu so you know which printer is which when you click on the choice? Thank you for a very good universal slicer.
