thats a nice idea.
as an alternative have a look at https://www.reprap.me/auto-leveling-sensor-module-film-pressure-probe-type-with-signal-cable-for-3d-printer-e3d-v6.html
the bonus with that is that you can reduce the mass of the effector since the probe is gone.
@snoozer I have found the service from Ooznest to be first class and have no hesitation in recommending them. Of course, they don't do a 3D printer kit so I understand why you chose RatRig.
Re CNC mill. I guess it depends a lot on what you want to do with it. Most of the OpenBuilds designs that I have seen are more what I would call CNC routers, rather than milling machines. For operations such as drilling, you need a lot more Z travel. I'd be a bit concerned about the rigidity of the column on those OpenBuilds designs that I've seen which have a reasonable amount of Z travel.
If a router type CNC mill will do what you want then fine - go for it. If you want to do more than mill slots and shapes, then I think you need cast iron slide ways, with "T" slots that you can clamp a vice to, a very rigid column, precision ground spindle, adjustable jibs, etc. Personally, I need to machine mostly small aluminium or brass components and for my usage case I'm looking at buying a "proper" milling machine then maybe converting it to CNC at a later date. The conversion shouldn't be difficult - at least for a 3 axis machine. It's more less just a matter of replacing the hand wheels with stepper motors I'd have thought.
@fcwilt said in Presentation of my CoreXY - PULLEYX-CUBE:
I notice that you are using a number of G4 "dwell" commands - are they necessary? ...
this is a habit of old times ... no idea if it works without it, but I think so
You can use Duet Web Control or PanelDue to simulate printing a file, which will give you an accurate print time. In Duet Web Control, Go to the GCode Files page (or GCode Jobs if you are using DWC 2.0beta), right click on the file you want, and click Simulate. When the simulation completes it will tell you how long it will take to print. It also writes the simulated time to the end of the file so that it can be retrieved later.
PanelDue and DWC 2.0beta display the simulated print time as part of the file properties. DWC2.0 beta also uses the simulated time to give you an estimated print completion time when you come to print the file.
@danal said in CNC uses...:
about fusion360 post processor, guffy made one for the mpcnc that provides gcode for marlin grbl and reprap firmwares (last one for the duet 3D).
i think it worth looking at it, it can handle manual change tool etc...
Cool, I will keep my eyes peeled for them. I don't like mix-matching bearings and surfaces anyway, manufactures have their tolerances, there isn't a strict industry standard, found this to be true with lead screws and leadscrew nuts.
What I mean by less steppers, is there is no real Z axis for delta, so gone is 1-3 steppers, no lead screws, no Z rods.
The optical ones supplied with the TLM work just fine with the Duet as is (well mine do) and I have a few spare ones that also work fine, it's just that the led switches on and off so fast that could be confusing you.
The bed is "mostly" an afterthought at this time because I don't know what that the final geometry of the printer will be. I want to get a rigid platform first, then get the arms on, check if everything is level. I have two sets of arms in development.
(Building the printer is more fun to me that 3d printing. Totally fun! trying stuff.)
Once the geometry is solidified I will do initial testing w/o a heater.
I am considering a bunch of options - I don't know the final diameter of the printer
---(thinking about) separating the heater from the printer entirely with a keenovo solution
-- also thinking about http://www.zyltech.com/zyltech-3mm-400x400-heated-bed-kit/
--The Wago 221's are rated to 20 amps.
--I am not going to run a DC heated bed through them (low voltage is higher amps)
--I will run the heated bed through an SRR
I'll take a look.
Thanks for the fast answers.
I've been working with Marlin and Smoothieware, but the Duet it's a superior solution to anything I have seen. Congrats and keep up with the excellent work.
I can't recommend these enough.
I don't have a delta with a smart effector, but these 30mm fans are quiet but still competent for cooling the V6.
Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
