Printing PLA is vitrually impossible. I have tried many different settings but there is hardly any fiĺament flowing out of the nozzle. I now understand that there is a V2 replacement.
First how do I know the version that I currently have to prevent wasting money.
Secondly I read that not only the hotend needs to be replaced but other components as well. So what are they.
An finally will this resolve my PLA printing issues. Since ABS warps like crazy and bed adhesion is generally also an issue I feel that after endlessly producing waste it is time to get rid of the M200 since I now feel quite hopeless.
Hi,
Please, refer to our tips for printing with Z-PLA Pro. A dedicated hotend only for printing with Z-PLA Pro is a must.
As for the hotend version - refer to the photos below:
Hotend v1
Hotend v2
As for other components - check if you have the newest extruder PCB version. You can refer to point 11 here. If you have the old PCB - replace it with a new one and apart from the hotend - install new heater&thermocouple as well.
Warping issues - I am sure you will find our troubleshooting manual helpful.

Hi,
No, this is the other way round - just as I listed above. However, the hotend v3 (dedicated for M Plus Series) looks similar to the v1 one - thus, you might have mistaken them.

I have this hotend on my M200
It has always bubbled through the top of the hotend (around the two black screws),. Per the Zortrax Service Documentation (Hotend Replacement in M Series 3D Printers | Zortrax Support Center) if your M200 does this you should replace your hotend with a V2.
I found that disassembling and cleaning (acetone soak) the hot end improved performance. In doing so, historically, I would remove the PTFE tube. Apparently the tube can only take so much of that and it tore up in attempted removal.
Question 1: Do I actually have a V2 hotend? (previous comments are a bit unclear to me)
Question 2: Can I run the hotend without the PTFE tube until replacement is obtained?
Question 3: What is the size of the PTFE tube in the V2 hotend?
Thanks - rrr
Hi @rrroadster,
the hotend shown in the picture is a V2 one. However, if the material still leaks through the top of the hotend even after replacing the part - the heater&thermocouple might be at fault. As for the teflon tube - unfortunately, we cannot provide its size, but the hotend cannot be used without the tube. Please note that the hotend is a consumable part and its approximate lifespan is around 350 working hours. Thus, the part should be replaced with a new one.
Best regards,

Hi Karolina,
Thanks for the reply. Regarding the top side bubbling and heater/thermocouple association. Is this due to too much heat from heater/thermocouple?
Cheers,

Hi,
yes, malfunctiong heater&thermocouple may cause the given issue. Also, it is important to make sure the teflon tube has not slid out of the hotend. However, if such a problem occurred while printing with a brand new hotend - this could indicate its manufacturing defect.
