Ok that makes sense. To your point about M141 S60. What if I wish to use the board to control when the chamber turns on using my slicer? For instance, I use E1 (second extruder) to turn my chamber on, there will be a thermistor in the chamber for feedback. Do I use bang bang or PID? I would assume bang bang. Where does M141 S60 come into play? I may have forgotten to mention, I want the chambeby VTE - Duet
Thanks for the info David. Here is another list of questions I have compiled in the last 2 hours. I am trying to use the E1 output to control a chamber heater. I want to make sure my gcode is correct.

Awesome thanks for the info david. I bought a PT100 and amp board that I wanted to use with my ramps but I never ended up using it. I want to get the duet running on a 3950 and then I will switch to PT100s. I had a question about my configurations. I am generating my gcode using this 'configurator' application. I'm at the part where it asks for bed probe info. I am using your Mini IR probe.by VTE - Duet
I will be doing the temp probe calibration that you did Calvinx66. I just find it silly that it is not plug and play. The 100k 3950 probe is so common, for the price of the board and the advancements it has, why can't it just read this thermistor correctly? Not hating, just a suggestion for the future. I dont know why it cant read correctly, and now I have to spend a few hours to get it to work rby VTE - Duet
Nevermind I got it to connect. I had 4 other things plugged into a USB splitter hub and that must have caused the Duet to freak out because too much stuff going on through one USB port. I guess as long as you keep everything else off the USB hub, it connects.by VTE - Duet

I successfully flashed the 1.14 firmware, thanks for the help. But now when I open arduino and try to open a serial monitor, it sends me an orange message "Error opening serial port 'COM25'.

One more question. I am trying to configure my G code endstops. I have two endstops, one for X and one for Y at the minimums. In marling these are called MIN ENDSTOPS, but I see a different nomenclature for this for reprapfirmware. It calls them LOW END or HIGH END. Is it safe to assume I have one end stop each on the LOW END for the X and Y axis and a Z PROBE? I am using this configurator asby VTE - Duet
Hello thank you. I installed the support packages via the boards manager, for SAM Boards (32 bits - ARM). I looked through C:/myusername/applicationdata and also a file called appdata, I found roaming but only my Slic3r folder was there, not bossac. Local also did not have Bossac. I am not sure how to get the firmware uploaded at this point. I will keep looking. I also did show hidden foldeby VTE - Duet
Thanks for the input on the temp probe. I will take a look at that. But before I do, I need to update my firmware and I am having an issue locating the Bossac program. I have arduino 1.6.9 installed on my computer and I could not find bossac in the arduino tools directory folder. In fact I did a quick windows search and couldnt find "bossac" anywhere. Is 1.14 the latest firmware for the duet?by VTE - Duet
I am also trying to set up auto bed level compensation, I have the mini IR probe. Is there a good how-to for this? I was looking in my homex.g script and I dont see anything there regarding setting up some auto level compensation feature.by VTE - Duet
Hello, I have done as much reading as I could on commissioning the Duet. I have run into a few roadblocks. 1. The SD card that was supplied with my Duet has Kossel configured Gcode in the SD card. I need to change this to a cartesian style configuration. I downloaded the Ormerod-2 'sys' folder and named it 'sys', I then put that in place of the current 'sys' folder that had the kossel confby VTE - Duet
I am using an inductive proximity probe for ABL and I want to boost its range, do the voltage divide resistors effect this? If I use a 100 and a 150, is there a better combination out there? I also measure 3.4v on the hi side, this is a little low on the voltage, should I be using different resistors?by VTE - General

Hi, I am running arduino/ramps/marlin and I am using an MK2a bed at 12v powered through ramps. I want to switch to a SMD embedded MK3 aluminum bed. Must there be a change in the firmware for this thermistor and if so, what is the change configuration.h? Thank youby VTE - General
I just noticed something strange. I uploaded my firmware with a z offset of -4.5mm. When I run the machine, sometimes it requires me to go up to -6.5mm because the nozzle is floating in the air. I use the LCD screen to do this and I retry the print until I hit the right offset. Then for some reason it jumps back to 4.5mm or the whereabouts, usually its off by a couple 0.01mm's. Point is, this maby VTE - General
Hey everyone. I installed auto bed level systems on 3 of my printers. I went through dozens of iterations on the best servo/switch/bracketing designs. I nailed down my auto bed level repeatability of the probe to a standard deviation of 0.01 or better. The problem is my Z offset changes from print to print. If I am lucky I can print 3 or 4 times in a row without having to mess with my Z offset.by VTE - General
Forgot to add, the arm doesnt retract between probing each point of the auto level grid. It ONLY retracts once after it finds Z home and then begins the grid routine. This is the most crucial measurement, once Z home is located, I dont want the servo arm to retract (which it does now). I really would like to learn how to do that.by VTE - General
QuoteAndrewBCN QuoteVTE Hi, thank you for the quick response. I am mounting them up. Here is the issue that I noticed, the PCB is not perfectly flat, the middle is bowed up and the corners are about 0.5mm away from the glass, this is where the problems seem to stem from. Poor conduction due to little or no contact. I was thinking bonding, squashing, gluing, or somehow fixing the heater to the gby VTE - General

I was reading somewhere that installing the MK2 upside down puts down more heat. Is that true? The thin glass from picture frames, is that stuff going to break when heated and cooled? That glass is not tempered. The machine is encased in a box and the electronics have a dedicated cooling fan, so it has plenty of power and no cold breezes. The bottom of the bed currently has fiber insulation. Tby VTE - General
I had the same problem, I used a big servo for my auto bed level and the board would reset when it tried moving the servo. I use a smaller servo now with no problems. Although, I did supply 6V from a dedicated BEC and that worked fine with the big servo. Just more stuff to wire.by VTE - General
