long time lurker here i have 2 duet 2's. one printer other is on small router im building. im also cnc machinist/programmer for 20 yrs. Mastercam, Featurecam, Powermill and WorkNC. 9 axis lathe w live toolng part transfer mill horiz and vert. lately doing lights out programming on 3 spindle horizontal mill cell with a thousand tool magazine.

F360 is based on the powermill/ feature cam engine but i dont use F360 i have a seat of featurecam i got from doing beta testing years ago. and im making my own post proccessor.

in 5 axis world it comes down to does the workpiece tilt or does the head tilt. the simplest solution is fixed spindle and a roll tilt trunion(yaw) holding workpiece. xyzab(c) sometimes axes. this is what most of my experience is on.

if the head tilts it ges interesting cause you have to know the length of the tool sticking out so you can figure out the cosign of the tool tip. most machines use something called tool tip comp(TCRP) where the controll uses the gage length and figures out for you behind the scenes where it should be. this magic number comes from a very expensive tool setter or a tool setter in the machine itself.

would start with 5 axis positioning establish a WCS from there and use 3 axis code you will be able to do most things his way from a cnc point of view. if you want to use a 4th axis to engrave a cylinder use axis substitution ad wrap the x or y around the a or b.

the biggest hurdle is lack of cutter comp G40 G41 G42.

your going to have t cough up big money for 5 axis cam software and having a good post processor. but most 3 axis freemiums will let you tilt the part establish a wcs and make 3 axis code

then there is programming in euler angles...... but thats a different story

join the EAA for40$ a year get maker/student version of solidworks 2019 mine will make toolpath. with cam option installed

fyi i love solidworks for cad, for cam its a turd with a rough learning curve,, but 40$ a year cant beat it.

disclaimer: im not gettng a kick back from eaa i dont own a plane or building one.. and i use old versions of mastercam and featurecam for CAM, if i didnt i would use it for my hobby ventures. ive been a cnc machinist/programmer for 25 years

im building a router and if noticed that there is no feed hold button/cycle start button that is real time, or single block mode. also no ability to see the next line of code thats coming up. even with a panel due. i am a journeyman machinist and i use these features every day to keep from crashing and generally doing things the safe way.

i have 2 duets one on my printer the other going on this router but a lack of these features may have me look elsewhere.

is it possible to use a duet as a dumb motion controller with input from mach3?

cutter comp is also on this list but i can work around that one

Ive recently been getting under voltage warnings when shutting off 24v power via relay and leaving 5 v on using pson pin. the 5v side is on a going into board at pson 3 pin header via a buck converter powered by the same powersupply as 24v side. its been wired like this for 3 years this is new behavior with 3.5.1. the 5v buck has its own direct wires to the psu.

its a 2017 vintage duet 2 ethernet.

im having similar disconnects and I'm on ethernet with a direct run to the switch that the pc i print from is plugged into. started with 3.5.1. duet 2 ethernet 2017 vintage. I noticed it happens when i pause (m226) to insert a nut to be printed over. ftp and telnet are off.

@deckingman
awesome thanks!! dont know why i couldn't find that page in my search. im surprised that little screw terminal can handle 6A.

i have a Duet 2, I haven't found max current specs for the hot ends. im wanting to run two 60 watt heaters at 24V on an idex printer. so they would both be on at the same time. is this within spec? or do i need to look at ssr/mosfets?

Ae you testing this with the reported machine position or with an actual test indicator?

Im getting around +/- .0004(inches) with IR switch and +/-.0006 with clicky switch with roller lever. ten hits discarding the lowest and highest avg the rest, with a brown and sharp 50 millionths test indicator (inches) it was calibrated 5 months ago. first touch was 3000mm/min second @100mm/min. i dont care what the machine says its at the indicator doesn't lie.

I don't do sensorless homing running your machine into a wall to home it just doesn't seem like a good idea to me.

I want to make a tester with an as5600, esp32 and a little lcd to keep track of the rotations as sort of a lost steps checker i can slap on if i suggest shennanigans are afoot if i zero it at x0y0 print go to x0 y0 it should read 0

either switch is accurate enough for a toolchanger. btw real cnc mills have about 5-10 of the clicky type switches in the actual tool changer mechanisms to tell the control where everything is at incase something doesn't get where it needs to be on time the tool change cycle will alarm out and stop before it starts self disassembly.

your not really after accuracy you want repeatability. if it repeats accuracy is the easy part.

i would like to make some code that totals machine power on time, print time and total filament extruded. i speak g code for a living but the conditional code has me stumped. i imagine this will write to a file on the sd card. im using a duet 2 setup as cartesian IDEX. i only have one filament monitor but will add another soon.

if there is an example file or how to please link me to it.

Gracias

did you store your values with config over ride or actually add it to main config? i use 3edv6 w 60 watt heater no sock never used a sock not gonna start . i have a wire brush that deploys and scrubs nozzle at start of every print sock would last long. i was over shooting by 20 degrees

i deleted config override and added autotune code into main config works fine now. autotune will give you a line of code in the console when its done add/replace that where your heater is at in config. dunno why m500 wasn't sticking for me.

hope this helps

@miss-rebekah

i figured it out since I'm using work offsets for tools i wasn't calling a tool number once i did that m3 works

@jean-baptiste
tool changer aside are you using a trunnion or a tilting head, does work piece move or does tool move?

have you done 5 axis programing before? what software are you using? im fluent in masterscam powermill work NC can get by in a few others. maybe i can explain it a little better. have you tried it with just one tool? how are you setting your tool length and finding centerline on the trunion(if using one)?

any hooo

If you draw your part in cam software the correct distance from centerline of the trunnion x,y,z, your ucs should be the point all these axes intersect at machine zero. and your tool tip is touched off in the correct spot that your machine is setup for the software does all the math. the duet is just playing back the g code it doesn't care how long your tool is. this is for a trunnion style machine. as far as the tool changer goes gonna have to get that from someone else but i know people have made macros for tool setters in this forum. usually this is done with G43H(tool number) but not on a duet.

i have never used trig functions to set an offset on a machine tool. well i take that back i have twice but it was a work probe hitting a spherical tooling ball at a known angle i think your over complicating this unless your spindle is tilting then i don't think it will work

@dc42
thanks DC42 your active participation on these forums is why i bought 2 duets. its actually working quite well for what I'm doing with it except for the above mentioned features. skew correction does have one big downfall on a lathe that is drilling you get x and movement instead of just all z i ended up popping it loose and squaring it the correct way. i made an aluminum tool holder to hold a tiny boring bar it had to be on centerline so i put drill in spindle and drilled it on the lathe itself. during dry run i saw the x stepper moving.

i did find another glitch if a start a spindle M3P0S5000, then send M3P0S8000 in iso g code and every machine tool i have used the spindle should accelerate to 8000rpm on my duet 2 on this lathe it wont change speed. it will if i give it M5 then send M3P0S8000. its the same in a program, console and DWC. I'm using heater 3/4 2000hz pwm the duet does not change pwm value. id like to be able to ramp up the spindle rpm without stopping m3 sxxx g4 p500 m3sxxx+1 etc.... bug,feature or operator error? i would think with ability to change rpm without stopping and a spindle tach knowing where your at in X constant surface speed would be possible pretty easy. i only code in g code for a living though
