Re: Next generation Duet

We have allocated boards to our beta testers, and we will have some pre-production boards left over from the beta test programme. We are selling these at the heavily discounted price of £55 + carriage + VAT if applicable. In return, we hope to get useful feedback from you. ... Thanks to all of you ...

Re: PT100 reading 2000°

If you want to try it, it's at m. All I have done so far is load it on a printer and check I can home the axes. OTOH the Duet WiFi build f om the same source code has been working well today, although I haven't tested the RTD support in it. If you get a temperature spike with this version, please lo...

Meh. WIFI ;( sad to see the wired port eliminated. I find that WIFI is just is not as reliable or fast as wired. why not leave Ethernet port and let people use a wifi dongle if they want wireless?

Re: Next generation Duet

I should add that the hardware design is now frozen. We did take user requests from a couple of other 3D printing forums during the design process, but not from this one because I only joined it recently.

Next generation Duet

Some of you may already be aware that a new Duet is in the works. This is a joint design between Escher3D (basically me) and Think3DPrint3D. I am pleased to report that after several months of development, the prototypes are working well, and we have just commissioned a small run of pre-production b...

Re: PT100 reading 2000°

Thanks, the "Hardware error" is the message I was looking for. When that error occurs, the firmware currently doesn't allow any retries before raising an error. I'll change that.

Re: Duet and Multi-Color/Multi-Filament Extrusion

A couple of suggestions: 1 You can do retractions and reprimes in the tool change files if you want, as long as you allow for getting a reprime at the start of the print. 2. To prevent oozing, make sure that the nozzle standby temperature is low enough. For PLA printing I use 150C standby temperatur...

Re: PT100 reading 2000°

I have taken a look at this. For some error types, the firmware allows several attempts to get correct readings, but for others it flags a temperature fault immediately. When a temperature fault occurs, there should be a message written to the GCode console in the web interface and/or the USB port a...

Re: Auto Calibration Standard Deviation

Mine is currently 0.035mm using 13-point calibration over an area a little smaller than 300mm diameter. I am still getting a slight tilt of the effector when it moves near the Z tower, so I think I still have a small geometrical error.

Here's what I _think_ are the relevant motor settings: M906 X1200 Y1200 Z1200 E1500:1500:1500:1500:1500:1500 ; Set motor currents (mA); set each extruder explicitly M906 I100 ; Set motor idle factor to 100% while testing so they don't idle at all M201 X1000 Y1000 Z1000 E1000 ; Accelerations (mm/s^2...

Re: Stopping initial retract?

We recommend using relative extrusion with RRF, because it avoids rounding errors, avoids issues with resetting the extruder position to zero, and is IMO more logical. However, absolute extrusion should work too, provided that any prime or retract commands you have in tool change files, pause.g, res...

Re: Weird offset error...

It could be that you have your acceleration set too high and it is trying to do a fast travel move that needs more torque than the motor is providing. What do you have the acceleration set to (M201 command in config.g), and what is the specification of your stepper motors? If you have the Duet insta...

Re: Panel Due Fuzzy?

The version 1.1 board can drive the 7" display as is, it's the version 1.0 board that needed a jumper wire added to the back of the board. Make sure you have the voltage jumper in the 3.3V position. The cable supplied by T3P3 is intended for the 4.3" display that they supply, but It's prob...

Re: Panel Due Fuzzy?

It could be a power issue. If you have a multimeter, check that you are getting 5V between the 5V and ground input pins of the 4-pin connector on the PanelDue control board - that's the two pins closest to the mounting hole. Don't try to run a Duet+7" PanelDue from USB power to the Duet alone -...

Re: Duet + E3D Volcano = WTF?

Although the nominal B value for the thermistor supplied by E3D is 4267, if you look at the datasheet then for temperatures around 220C a more accurate value is 4388. It makes around 7C difference AFAIR. It's quite difficult to get good thermal contact between a thermocouple and the heater block, so...

Re: PT100 reading 2000°

A few suggestions: 1. Your photos show 5 or perhaps 6 wires going into the terminal block of the RTD board. How do you have them connected? 2. If you choose a different RTD channel (say X201 instead of X200) and send the M305 command from the console to select it, do you get an error message? If I s...

When you issue the M305 command with X200 in it to enable the RTD channel, is an error message displayed, in the gcode console tab of the web interface, or in your USB host program?
