Hello. I have implemented M572 D0 S0.1 and there has been an incredible improvement in the quality of prints right out of the box. I can't even begin to understand what exactly is going on. I now just get a few tiny blobs on the outer perimeter after a sharp corner. Extruder is calibrated just right. Was wondering if I can tune these blobs out by changing the S parameter of M572. In other words iby lide - Duet
The printer is built in a plywood box so that takes care of the bottom and 3 sides. Made a hood with 2 plies of thick plastic bags. And a 'door' with 2 plies of corrugated cardboard held on with magnets for easy removal. The pics make it clear.by lide - Duet
Thanks for the clear instructions David. Made a little circuit for this and it just worked. Enclosed my build chamber too and it stays a toasty 53C with a 100C heated bed. No additional heating needed. It's comforting to know that the duet can control an external Mosfet/ SSR to get an even higher temp if required.by lide - Duet
Hi. I'm looking to deal with ABS warping issues on my corexy so have started enclosing my build chamber and hopefully the heated bed will reasonably maintain the chamber temperature. I want to use the expansion header to monitor the temperature in my heated chamber. I plan to simply attach a thermistor between the AD7 and ground pins on the header (it's a duet 0.6). Is this correct or do I needby lide - Duet
Hello. I have a corexy running on duet 0.6 and dc42's latest firmware. I have an approx 500mm Bowden tube and am using retraction and coast in S3D to manage ooze, blobs and stringing. The discussion on this thread has got me interested in trying out the pressure advance feature. I have a few questions about this. - It seems that all I need to do is add M572 D0 S0.1 in config.g to tell the printeby lide - Duet
Thanks dc42! I also found this thread that gives great information on these kind of sensors. Fortunately I have an NPN sensor so it plugs in directly. Added the second M574 command and it works fine now. By the way I had a chance to go through some of the code for the firmware on Github. Everything is so elegant and easy to understand. Beautiful piece of code. My compliments to you and thanksby lide - Duet
Hello. I use an inductive proximity sensor as a z endstop and z probe on my corexy. I've just finished wiring everything on to a duet 0.6 with firmware 1.09r-dc42. The inductive sensor gives a 5V signal when not triggered and grounds the signal when triggered. I've used a voltage divider to bring the signal down to 2.4V and feed it to the E0 end stop pin as described here . My config.g has thisby lide - Duet
Thanks for the great inputs. I decided to risk it and run 24V to the bed through the mosfet. Gate signal is the bed output on the board (Ramps for now but I'll report back once I shift to Duet) so I get over 10V. I'm using bang bang if that makes a difference. Datasheet for the mosfet says 0.014 ohm corresponding Rdson. Even at 18A I figure I need to dissipate just 5W of heat. But I'm paranoid soby lide - Duet
Thanks for the quick reply dc42. The heated bed does indeed have both a 12V and 24V supply option. I currently run it at 14V on the 12V terminals and its still takes too long to heat up. I see that a 4 fold increase in the power being supplied to the bed is a bit extreme but I have seen various account of this being done successfully. The wiki entry for this heated bed too mentions that providingby lide - Duet
Hello! I'm new to reprapping and have recently built myself a corexy currently running on a Ramps board. I'm currently switching to a duet 0.6 board with firmware version 1.9r-dc42. At the same time I'm looking to switch the heated bed to 24V to get faster heat up time. The heated bed is a mk3 aluminium bed with a resistance of 1.4 ohm. I have a few questions: Can the duet deal with the ~18A poby lide - Duet
