@Sejl you don’t need a special post processor, just use a fanuc one and remove the canned cycles. All the Gs and Ms in every line are no longer needed, it behaves as a normal industrial Cnc, once a command is sent, all the lines following are under that command, unless you change it again.

RE: Real Time Position
Industrial cnc systems show real-time position of the movements. What I don’t know is if that position shown is read from the encoders or generated from the gcode. The control definitely knows encoder position off all axis and can make corrections.

RE: Slicer's What are you guys using ?
I used S3D for two years, I'm using superslicer now, and I'm very happy with it and get much better quality parts than S3D and CURA. CURA is slow. The only feature I missed from S3D is the ability to easily removed unwanted supports, appart from that, slicer works much much better.

RE: Request firmware config for concrete 3d printer
Hi! You should provide your specific hardware, movement kinematic, and extruder type before anyone could help you.

RE: Problem with babystepping V3.01 RC10 and DWC 2.1.5.
@Phaedrux said in Problem with babystepping V3.01 RC10 and DWC 2.1.5.:
So you're saying that if you set the baby stepping once during a print it is being applied again on the second print?
Thats right. It started since the V3 release. I forgot to mention that every consecutive print re home all the axis. I have a bltouch 2.0 and I get excellent repeatability when homing so I don't think thats the problem.
I'll try RC11 next week and test if there are any changes. -
Problem with babystepping V3.01 RC10 and DWC 2.1.5.
I have a problem sin V3 release, it did not happen with 2.05. When I start a print, if I adjust first layer height with baby stepping, lets say 0.1mm closing the gap between bed and extruder, and the print finish or I stop it and start another, the new job takes into account the previously set distance and re apply again, many times making the extruder touch the bed and I need to increase the gap the same amount I decrease it the first time. Im on V3.01 RC10 and DWC 2.1.5. Duet 2 ethernet.

RE: Building 1350mm x 2000mm CNC Table. Duet or?
I think It would be a good idea if a Duet3 CNC oriented board came out. RRF is great, and very easy to use, but as mentioned before all the boards are very 3D printer oriented.
I would like to have a Duet3 without drivers, thermistor inputs and heater outputs and instead have dir/step outputs and ethercat for the use of industrial servos. Another missing feature is an encoder input for a spindle, needed to do hard threading, and an addon board with isolated inputs and outputs needed for a CNC. Also an MPG input.
Software side, there are no fixed cycles (for now at least), which is not very necessary for a mill (or a router), except for drilling cycles, but it is really used on lathes, also tool radius compensation is needed for a lathe. Otherwise, everything needs to be done on CAM. -
RE: duet3 post processor for fusion360???
Fanuc post should work. I made one for powermill (it’s here on the forum). David fix the firmware some time ago so G1 and F commands are maintain until a change in one of those, which was the primary difference I found with industrial cnc controllers.
You should disable fix cycles in post or write the program without them (I don’t know how fusion works), since RRF doesn’t support them. -
RE: My multi input, multi material, mixing hot end
@deckingman said in My multi input, multi material, mixing hot end:
@fma I don't know what the boiling point of printer ink is, but I'll bet it would likely just vaporise if you tried to inject it into the melt chamber at circa 200 deg C.
There are liquid masterbatches, they are used in the plastic injection industry primarily for PET and PC resins, so they resist 300° C easily. They get injected with a peristaltic pump if I remember correctly, but you need a pump per colour.
Solid masterbatches won't work unless you have a very long screw, so I think not even pellet extruders might get consistent colors with that... -
Duet2 ethernet without drivers
Hi, I want to build my own injection molding robot and was looking the best hardware to do it, but I will use external drivers.
Will a duet2 or a duet3 board without on board drivers, aim at controling industrial servos only be made in the future?
I'm also considering machinekit with a beaglebone but since I become very familiar with RRF I would really preffer to use a Duet family product, -
RE: Smaller NEMA17 for the Extruder
@bluedust Hi, I have 801,81 at 16x interpolated to 256x.

RE: Smaller NEMA17 for the Extruder
I have the same motor with a titan extruder, which has the same reduction, 3:1, as the bondtech.
I used it at 1400ma with no problems, even with long prints. -
RE: External Heater Question
@pinkmaro you could control it anyway using the right SSR for that power.

RE: Direct-drive non geared .9 stepper?
I use the Titan aero, which is 3 to 1, with the e3d pancake 0.9 deg. at 100% current, which is 1400ma. I never have a problem, but I used to print with 0.5mm nozzle at 0.1mm to 0.4mm layer at 50mm/s. I never have missed steps. Although all my assembly is full aluminium so heat is not an issue.
I used to have an mk8 I think, and at some point I calculated the torque between the two extruders (the mk8 has a more powerful 1.8deg) and it was the same but with much more resolución which greatly improved part quality. -
RE: Autodesk PostProcessor for RRF
@timcurtis67 Hi, I was reading the help and apparently you can't dissable tool changes in powermill, it will allways write them with the first trajectory of a NC program. But I'm sure there must be a way to dissable them in the post, it's just my knowledge is limited, I simply edit a fanuc post and dissable eveithing I found that RRF won't interpret. You can write scripts, but I know nothing of programming.
I don't have the ability to post without a tool in powermill, but I don't know if you can in featurecam or in artcam.

RE: Autodesk PostProcessor for RRF
@timcurtis67 Hi, I'm manually removing the G43H1, I never paid much attention to it since I use it all the time on the machine center and when I occasioanlly don't need it, I edit the file. But now that I actually want to eliminate it I don't know how...

Autodesk PostProcessor for RRF
Hi, I've made an Autodesk postprocessor (powermill, featurecam, artcam) that works with RRF. It's still a work in progress but so far it works.
The only thing I was not able to remove is the G43H1 at the beginning, I'm not sure if it's post related or cam related...
Canned cycles are dissable.
Arcs works.I don't have a Duet controlled CNC yet, i'm putting my printer in CNC mode, so if someone can try it, let me know how it works.
Change .txt extension to .pmoptz

RE: Error: Bad command
Hi, I’m finishing a powermill, featurecam, artcam postprocessor for RRF. I think I’ll finish it after new year. It’s already working, I just want it to correctly output G2 and G3 arcs and be sure it doesn’t output any canned cycle since those are not supported.

RE: Firmware 2.02 released!
@dc42 Hi dc! I tested the new CNC mode, and it works fine now. The only thing I forgot to tell you was that It would be usefull if you can can add some G o M function to set a G0 speed, so that speed is fixed and only a G1 speed is set through the cam (thats the way industrial CNCs works). A workaround could be to tell the postprocessor to output G0 F1000 (could be any speed) instead of G0 only.

RE: OOZNest WorkBee, screw driven
With the latest rc7 firmware, fanuc postprocessor should work, I'll make a powermill post and post it here once it's done. It should be pretty easy now. It'll work with featurecam and artcam too.
If you looked for it, any cam should include a fanuc post.
