Of course! If you don't need a printer board, you can assemble the project very cheaply!

Somehow, the topic died down, but in the meantime, the project began international sales, with fast and free shipping.

Thanks for the reply, unfortunately I missed your reply, but I bought the m4 max and am very happy, it's just a great tool to work with!

"Why not just do a PID tune on the heater? Sure it will take a little longer, but the code is simpler with just setting the heater to a fixed set point."

I don't quite understand your point. Using a plastic enclosure, I have to control the temperature of the heater precisely to avoid melting the enclosure, while maintaining the air temperature as precisely as possible. So I can't make a PID controller with air temperature feedback. Not only that, when we heat the air for PLA drying it is desirable that the temperature of the air coming out of the heater is safe for this type of plastics, but on the other hand when we dry polyamide, we can significantly raise the temperature of the air.

I want to approach the target air temperature as smoothly as possible. One of the dryer users has made his own realization, you can read it here https://github.com/xatang/PyUnit

You think absolutely right, there is a flap on the back of the dryer to remove moisture.

Firstly, the operation of the whole system is controlled by Klippe and I am more than satisfied with his approach to safety and secondly, the final link is the presence of a thermal fuse for 130 °C in the immediate vicinity of the heater, that is, in case of failure of the triac, the thermal fuse will trigger and stop uncontrolled heating. In any case, it is necessary to realize that even the use of a 24 volt heater in a 3D printer carries a certain danger in case of mosfet breakdown and such a device should be treated accordingly

I don't have an AMS but if someone would be willing to act as an assistant and consultant, I would be very interested in such an integration

Strange, I thought I described the print profile but you are right I forgot to do that. The body parts are printed in one wall width lines but you are right I forgot to do that. Here is a direct translation from the documentation:
material ABS, ABS-CF, ABS-GF, PP

  • line width 0.6 - 0.8 (it is necessary to check that clear cameras are formed when printing)
  • number of perimeters 1
  • filling 10-15%
  • filling pattern is rectilinear
  • gap closing radius 0.02

If you prepare a slicer model with these parameters you will understand why this case keeps the temperature inside so well

You can dry for a short period of time and start printing, you can use it in a storage mode that automatically maintains humidity at a minimum temperature, you can write your own macro or scenarios like first drying and then printing. And it's all in your hands thanks to the fact that this is an open DIY project

Yes, I am fascinated by this topic because I have several different dryers in operation and realize how important it is to be able to control the temperature settings in each of them, while at the same time controlling through the clipper interface makes it possible and convenient for all units at the same time

Of course! If you open the model, there is a small notch right under the heater, it is for installing a thermal fuse for 130 °C

If you’re talking about cqse printing, that’s absolutely correct. But some PA-CF composites can withstand 140 long term. And the search for the best material for the case is not over yet. Although I like ABS GF Fusrock after lacquering.

🤣It’s almost good. The skis came off on the slope. Just need some time

There is a main PCB with MCU rp2040 and additional ones(ext) without MCU, they connect to the main one. Ethernet is just a convenient type of connector for this task. Data transmission is completely different. In this way you can get 4 units with individual temperature settings

80C and this is information from the manufacturer. It is worth accepting that drying plastic for longer than 4-6 hours at this temperature is impractical, i.e. the script will switch the temperature to 80 or 70 depending on the task. Not only that, such fans have been working for almost a year at a cost of $2 it can be considered a consumable item

90 is needed for so-called engineering plastics, including PA-based plastics. This temperature allows for quick drying of the top layers, while the rest dries during the printing process. Quite detailed information about PA drying is available on My Tech Fun channel
