Re: filaflex

filaflex has been around for a long time. its been awhile but i remember a comparison review of 5 or so flexibles. i remember the filaflex not being any faster. try the cheetah filament. its a little faster than ninjaflex but keep in mind any flexible will be slow. thats just the way it is

Re: M2 Fire Report

You cant get a true reading on the hotend with an ir gun. Its too precise of an area that needs a measurement. No small sensor is available for the block. You would need a second sensing unit maybe using a thermocouple attached to the block connected to a purpose built board

Re: M2 Fire Report

Yes, an i dependent over temp circuit is what is needed. A temp switch on the block that will shut down the power supply. Problem is lack of a temp switch or sensor that is small enough at the right temp to work. Last time i looked was about a year ago and there is just nothing on the the market. Th...

Re: M2 Fire Report

Thermistor goes bad, hardware component on rambo board goes bad, glitch in the firmware. Any one of these items would have to fail in a way to keep power on constant to the heater cartridge. I have watched a forced failure video awhile ago. The cartridge will melt the aluminum heater block and catch...

Re: M2 Fire Report

Could there be a feature (or accessory item), which monitors if filament is no longer extruding during an active print (i.e. filament is stuck in the hot end), which after XX amount of seconds it will power down the hot end and printer to prevent any possible issues. There are devices on the market...

Re: M2 Fire Report

Yeah they are polyurethanes. I think its less about the material you are printing since there is very little there. Its the abs plastic prinded parts on the printer used in the whole extruder.

Re: Low extruder torque -- is that the pinion gear?

yes it will click and youll get some under extrusion. i dont think mine really got weak. it just started skipping and making the click. you'll also notice you will slowly have oozing issues that get worse and worse since the retraction is sloppy and not to the distance that it is really set to. i ha...

Re: M2 Fire Report

i have always said that 3d printer of any make and model need a secondary, independent overtemp shutdown. i have looked for small thermal switches before but like insta, i have not been able to find any with a high enough temp. i am actually surprised you dont hear about more accidents like this hap...
