Re: Mods.. (The Good, The Bad, The Ugly)

I just put a Bondtech direct driver extruder with an E3dV6 hotend on my Rostock Max V2 Franken-Printer. Instead of using a stepper from E3d that is .9 degrees I used a RobotDigg 1.8 stepper which weighs in at 200 grams; both these motors are equally as wimpy @14nm. E3d suggested that if I go to town...

Re: Duet Tuning.

Made this change and test. (E3d) Configuration.h #define EXT0_TEMPSENSOR_TYPE 3 That is really cool... I did not realize the firmware was accessible on the SD card (not having looked on the SD card)... I will take a look at the SD card.. Also I am will test putting the thermocouple into the hot end...

Re: Mods.. (The Good, The Bad, The Ugly)

Here is an idea for a partial enclosure; not to keep heat in; but to stop cold air from rolling into the printer from the adjacent window.
A piece of Lexan would work too... but this is much cheaper.
Thoughts?

Re: Enable strain gauge Z probe?

Good to know that G32 is really checking how the effector travels in a plane. There is not much error there. The elements involved in moving the effector are the least rigid - belts - arms (they are pretty ridgid). With a extruder mounted on the effector I am introducing more mass into the most flex...

Re: Enable strain gauge Z probe?

My current thinking about "auto leveling" is that the Artemis being very ridged, and the bed being very flat; that there is really no reason to auto level. On the rostock max you have to correct for differences in tower height by fiddling with the endstop screws. Here you can do that in so...

Re: Mods.. (The Good, The Bad, The Ugly)

It's more likely that I'll give up on the SE300 and install a e3dv6 though. I am still very surprised that an effector mounted extruder is far superior to the bowden configuration, even without cooling. --I am even getting better prints by disabling zhop... Z hop of .3 is still required for the sup...

Re: Duet Tuning.

Ok.. this is with an E3d thermistor.. properly calibrated.. Duet is reporting 200.. the thermocouple is reporting 220... @ 195 I am reading 215 @ 190 I am reading 210 (I will just print low.. | its hard to figure out what is the correct temperature) The temp is rock solid http://i.imgur.com/ZY7XXrM....

Re: Duet Tuning.

I finally got in a handheld thermocouple. I am using a Biqu thermistor. The advantage is that the resistor is prewired in a home run and fully wrapped. I found that unless you secure an E3d thermistor down properly the wires break off from the connector. The problem with the Biqu is I don't know the...

Re: Heater issues

You do an

M303 Heater 1 Temp 210
M303 H1 S210

Followed by an
M303

Write the parameters down

Then check config.g and config-override.g
Under M307 command you should see the parameters you wrote down.

OK, at present this just seems to be an issue on warmup not when the hotend is up to temperature.

There is no M307 in the default configuration file for H1

Re: Duet Tuning.

I changed the thermistor I am getting some heater fault errors due to what I think is a slightly lower heat up time Actually I think it may be a much larger mass that needs to heat up in the Titan Areo (and I am not using the E3d thermistor because I don't like the fragility of them) temperature ris...

Mods.. (The Good, The Bad, The Ugly)

My original intent was to keep the Artemis in a solid state from the factory; instead I am using the machine as a "lab machine" (with my Rostock Max V2 being my main "production" machine). It's not that the Artemis needs to be modded in any way as its very much turnkey. If you ma...

Re: adarcher's build/troubleshooting

First layer problem could also be z-offset. You can also baby step the effector up/down a bit interactively using the duet interface. The printer could be set too fast as well. (and for me I find the software/programming/gcode aspects very challenging - not easy, with the mechanical stuff being the ...

My perception is that the machine was designed to be turnkey (even with some state of the work leading-edge features) I would suggest that the machine be restored to "factory defaults." (do it yourself/ask to have it done/pay to have it done/ if you are NY? ) If bed leveling is the issue, ...
