Thought it would be interesting to compare the size and bulkiness 
Pre-orders open up this week for a limited amount.
EDIT: Now available for pre-order at http://deltaprintr.com/shop/parts-and-accessories/hardware/mini-hotend/
I will most certainly be getting my hands on one:-) awesome job. If it works as well as it looks I will be buying quite a few.
Any ideas on price or do I have to wait till preorders;-)
@Griffin_Paquette Pre-orders will be at a discounted price of $39. Production on the hotends has already started and we should hopefully get them from our supplier within a month.
Sounds great!! Not a bad price either:-)
Nice! I need to preorder one as well.
If I’m coming from a v6 how would I mount this one?
Link to preorder?
@Guy_Bailey This one gets mounted from the top using 2 M3 screws (not included).
@Nathan_Walkner No loss in anything.
@Mike_Miller Not available yet on our site. Will put it up sometime this week.
How is the thermistor mounted?
If it’s all metal I’d love one one
U have enhanced nozzles as well?
@Glenn_West It’s mounted on the side (not shown in this picture) and held in place with a sleeve. Works pretty well.
If you mean hardened nozzles, we are going to release a sapphire nozzle pretty soon rather than hardened nozzles. It’s much better than hardened nozzles.
Shai, I love what you have done with the heater block.
I would like to purchase a hotend and a spare heater block for tinkering. Are these up on your website yet?
Not yet, these will be available hopefully by end of this week for pre-order. They will sell as a complete set, not in parts.
Gotta get one. What’s the overall length? Looks like about 45mm…
@Whosa_whatsis I have to check. Fan is 25x25, 2.1mm break, 2.5 hex on both ends, 10mm heater, plus the nozzle… about 32mm plus nozzle… I think.
No loss in anything? I gotta believe it would have trouble keeping up with fast extrusion on certain setups. There’s just so little thermal mass. What’s the most volume (mm3/min?) you’ve been able to push through it?
@Taylor_Landry Yes, the thermal mass is low, but the sensor is also closely-coupled to the heater, so the feedback loop should function quickly. Ideally, the temperature sensor (which would ideally be a thermocouple rather than a thermistor) would be in between the heater and the nozzle. As it is, the melt zone may cool a little, but if there is good thermal conductivity between the heater and the nozzle it should be able to respond quickly to a drop in temperature by increasing heater power.
High thermal mass provides passive temperature stabilization, but low thermal mass combined with fast feedback from the temperature sensor allows active temperature stabilization, which is arguably better if you can get it to work right.
@Taylor_Landry We haven’t compared it to the E3D in terms of extrusion speed, so I can’t say. We print at around 60mm/sec on our new Delta Go using Cura.
If you’re curious to see some printing videos with the new hotend, you can do so here: http://instagram.com/deltaprintr
@Whosa_whatsis Pretty much nailed it. It works great with smoothie ware’s ability to do auto-PID tuning. Haven’t tested the hotend using marlin yet, but there shouldn’t be a problem. We use the new Semitec thermistor (the old one is obsolete) and considering I haven’t kept up with Marlin lately much since we’re switching to smoothie… I don’t know if the new thermistor has been added to Marlin yet. if it hasn’t, you’ll need to create a thermistor table.
BTW, Roy Cortes took some thermal images of our hotend… he said it works pretty well. I have asked him to send me the thermal images as we haven’t had the chance to do that yet. Will share them once we get them.
@Shai_Schechter What’s the mounting pattern on the 3mm holes? I assume they screw into the top of the block? Any chance they’ll match a Kossel effector pattern?
