Unclipped the cables and allowed the cr touch cable to float free and problem solved. Moral of the story, don't get too obsessed with tidying the cables.

In the end it turns out the when I cable clipped the cr touch cable near the hot end it was so tight that with the mnovement of the head the connection was being disturbed and the cr touch would just stop and not work, and sometimes the head would crash down onto the print surface because the cr touch had 'lost touch' with the processor board. DOHHHH! Homer Simpson moment.![]()

Cooling fan and heatsinks and maybe going to reduce bed temp qnd raise hot end temp and see what can do. Yeah a dedicated cooling tunnel for the extruder may work well.ankh wrote:Will, I have exactly the same issue E3 V2. Prints fine up to 35-40deg ambient temperature, anything more like that and it's clogging and extruder motor grinding filament. I tried many things - cooling fans, dual extruder, direct drive - nothing seems to work, 35-40 deg seems to be its top temperature. I could still do small prints but anything bigger usually fails after 1-2h. What I was thinking to try is enclosure for the printer and hook up portable cooling unit. I just can't justify the spend for several days of heatwave per year.
