While printing warp prone materials it is beneficial to maintain a certain chamber temperature before printing starts and through the duration of the print. Doing so I have had fantastic results with large PC prints with my X1’s. Better than any of my previous printers.
However, manually preheating the chamber by placing the bed at home position,stetting the bed to 110c, enabling the aux fan, and waiting has become a seemingly unnecessary process. Since all of the sensor data and elements exist already it would seem pretty straight forward incorporating this feature into a filaments profile settings to reach and maintain a desired chamber temperature. To maintain a temperature while printing it would be necessary to utilize the chamber fan if the chamber temp exceeds the set point like it does for PLA.
Hopefully this is something other people would find to be a useful feature request.
I’m pretty sure there is an option to add custom start code for each filament profile. Allowing you to automate your initial process (at least somewhat) by letting it heat the chamber for a set time before starting.
It’s not the dynamic control we would like to see but it might be a usable workaround?
Correct. However, there is not any translatable g-code I can find for chamber temp. All I could do is put in an arbitrary wait command several times with the bed temp set to a certain amount. That is what I am doing now but its not very helpful for any consecutive prints. I’d have to change the wait time for each print dependent on how long its been since the last print. I’d much prefer to utilize the sensors and data the printer already sees in a user friendly control feature.
I’m trying to print large PC components but am having problems with warping. I use the engineering plate, 110C, adhesive, brim, fans disabled. My chamber reaches to about 50-52C.
Could you be so kind to share. What works for you, what do you use? Also what temperature does your chamber reach and how long does it take to get there? Do you use extra insulation around the machine? Does the auxiliary fan speed up the heating?
I’ve been trying to google for supported max temperature of the chamber but couldn’t find much. It has been advertised to support 60C. How much can the machine take?
Googling suggests that 60C is good environment for PC. But I’m not reaching that right now. How to get there?
Good to see the fan control based on camber temperature is being requested on GitHub. I’d also like to see the implementation of preheating the camber also requested.
Please add this feature. Using Orca slicer and setting chamber temp on and temp to 50c nothing appears to be stopping the printer from starting at 34c.
Please add this feature. I am not a professional user hence I purchased an X1C instead of X1E. My time is free and I am willing to have longer print times for ABS and Nylon. Currently I set the bed to 120c + aux fan at 10%, then I wait till the chamber temp reads 50-55c before clicking “Print”.
Please please add a per filament option to automatically do this. Sometimes I eat hot dogs and forget the bed heater is on for hours.
The G-code we need is M191, which waits for the chamber temperature to reach the set value, whether it needs to rise or fall.
I currently use a custom G-code that sets the bed temperature and waits 10 minutes to allow the bed to heat soak. After that, for materials like ASA, PC, PA, or PAHT-CF, it should wait until the chamber temperature hits the target value.
Without proper implementation of this functionality, we’re stuck for now.
My shop is too cold in the winter to print even PLA without first preheating the chamber, so I can see how your code will save me a lot of manual monitoring and chilly trips out of my office. Thank you!
I do suggest you modify the description to indicate the code is really only useful for an X1C. The code will not work with a P1S or enclosed PIP because they lack a chamber temperature sensor. An X1E or H2D should not need the code.
Also, the code does require OrcaSlicer. Studio does not support the Chamber Temperature setting in the filament profile. The setting does not even appear in the Studio profile editor unless you first select an X1E/H2D printer.
