so i had rewritten the POCKETRECT milling instructions to be super efficient, no backtracing, and just too complicated. after several hours trying to adjust the boundary conditions - essentially when to reverse the tool travel - i went back to AI. i uploaded my current module and tried a new...

i actually ran the cnc router 2 days ago - total disaster. i had modified the POCKETRECT to make the tool follow an optimally efficient travel path and screwed up the boundary conditions and couldn't see the problem in the simulator. copilot couldn't straighten it out - must be my bad...

@2tiki - thank-you for the offer. i have been using ms publisher as a 2D CAD program - it has been adequate, could use layers, but now MS is going to sunset the program. (too bad for me as i have created almost 10,000 .pub files over the last 25 years for my art publishing business. probably...

really no clue at this point. i have to laugh - the output of the shop never matches the images in my head. compared to my digital world, 3D can be a bitch. must try this new cube design in the CNC router. it is incredibly encouraging to make this progress over the last 3 days ... after 3...

oh, yeah ... it was wrong about the header transformation - i just reset the values and it works correctly.

here is what Copilot did: Below is the complete modified G‑code for “SET” after a 180° clockwise rotation (i.e. a 180° rotation about the origin). In a 180° rotation every X and Y coordinate is multiplied by –1. (Z values remain unchanged.) For arc commands the endpoint coordinates and the...

CNC testing was delayed - waiting for a new bumpon (bottom corner foot) that go into a hole, instead of using adhesive to attach to the bottom. the problem with the adhesive kind, is the heat from the heater eventually softens the glue, and the foot can slip around. simple solution is to mill a...

4/20 update ... (was going to post this yesterday but not quite done) finally cleared my desk enough to once again get some solid time put into this project. the focus has been on the GCODE for the CNC router. the design has evolved from a solid 2" cherry cube, to milling the faces from a...

what is your triglycerides? my HDL is 85 and my triglycerides are 45. vaping has had no impact - diet is the key.

i didn't realize how addictive sugar is until i gave it up for 30 days. now i use sugar very sparingly - mainly to tamp down ketones if overstimulated. i think animal fat is okay if well raised - grass fed, pastured, organic, no RNA, no GMO, etc. yes to butter/bacon/red...

on demand is tough - that's what a BIC does so well for a joint. i can get the heater to 400°F in 10 seconds - still 10 times slower than a BIC ... but the heat transfer to the herb is too slow ... the herb needs a 2 minute heat soak at just below vape temp so that a draw can cause the final...

DMSO is supposed to deal very effectively with burns or other skin conditions. A Midwestern Doctor on substack has been covering it a lot recently. Amandah Vollmer also. Mercola reposts AMD. i got some DMSO and still reading the instructions/recommendations for use - but i would put it on a...

i feel for you. i save most of my injuries for the wood shop - tried to remove three finger tips when a dull 1/4" drill bit seized a piece of metal shim and pulled out of my hand and then sliced it. severed a non-essential tendon and some nerves - been several years now and the nerves still...

i use a dremel tool with a 0.7mm diamond bit to drill borosilicate - just submerged under water. there is a physical property/effect that allows drilling or cutting glass underwater without fracturing. videos on YT show drilling through the bottom of a ceramic mug under a water film.

@highvaper - is that nichrome60 or nichrome80 in the pictures?

i use slightly narrower nichrome ribbon - at 1/8" (3mm) - and it is about 0.3 ohm for 13" length. make sure the battery can deliver the amp demand. looks like you will pull >10 amps with shorter heater ribbon. could work with a single battery like LiFePO4 - mine can deliver 70 amps. also, i...

the corning references were concerned with liquid in the vial in contact with the borosilicate glass causing delayering/fragmentation. dry herb in the vial is certainly a different situation. although the vapor is "wet" and does attach to the glass surface. i had read before that borosilicate...

@Elku thanks for the bump. reading @vap999 's post got me to doing some analysis with copilot. and, yeah, borosilicate glass is not the holy grail i thought it was. it appears the main flaw in my design is the edges of the holes in the bottom of the borosilicate vial. i think i should flame...

pretty sure that heater coil is nichrome ribbon - probably 60 rather than 80. the ones i have seen will corrode from thermal cycling and nichrome80 doesn't. i used the heater ribbon from my car cigarette lighter in one of my first vape designs. even got a camping 12v battery to power it. my...

just to put the topic of spallation to bed ... i've been trying to remember why this term was stuck in my head. and i remembered that several years ago (original thread may 17, 2010 - search spallation) i chanced upon a medical article about spallation in tubing used for dialysis and i...
