Re: Liquid cooled heat sink for the Pro2

The water path is "U" shaped when viewed from above and goes around the throat tube. In, back, over, back to the front, and out. The throat tube is in complete contact with the copper heatsink minus the width of the clamping slit in the front of the block. That is inconsequential.

What happened to the "Save As"

I commonly pick a filament profile to use as a starting point, then do a Save As to create a new profile with a name of my choosing. The Save As button is gone from the advanced filament editing window. Was that done on purpose? Has really screwed up my process. Am I missing the trees for the forest...

Re: Liquid cooled heat sink for the Pro2

I have heard that some users who are intimate with the Pro 2 electronics have tapped power from the printer, but we simply use a standard 12 VDC power brick. We plug it into a switched box that also powers the printer. When the switched box is on, everything is on. Works fine.

Re: Liquid cooled heat sink for the Pro2

The net gain on weight after removing the OEM fan and heat sinks was very modest. The huge improvement in printing reliability was absolutely worth any negatives, and honestly we have not seen any detrimental effects at all. The stock air cooled heatsinks are only slightly better than worthless, IMO.

Hi Taylor, I have forwarded your email to my colleague who manufactures my heatsink design, however I am including his email here for you... penglish@englishmfginc.com He is a Pro 2 user as well and we both have many hundreds of hours combined on our Pro 2s without throat freezes since we changed ov...

Re: Liquid cooled heat sink for the Pro2

Shabby.... A very nice installation! The extruder motor cooling will definitely be of value. Not sure the axis drive motors need cooling as they can be hot to touch and not cause any harm. The hot extruder motors preheat the filament and that IS an issue for some filaments. I look forward to hearing...

Managing files on the Pro2

I am wondering if anyone else has found the file management on the pro2 to be as obtuse and "broken" as I have. Why is it that the Pro2 can communicate with a computer, but the computer can not see and access the stored files? I have tried everything I can think of to "copy" a fi...

Re: How to disable an extruder for using only one

If one disengages the drive pressure screw on the un-needed extruder then it doesn't need to be preheated to do the "dance" on start up. The unused extruder will simply push the filament up when the extruder retracts. You might take that into account when changing the firmware. The whole i...

Re: Questioning Pro2 Product Quality - Ongoing Issues

Well, as a senior career engineer, I have not worked for $20 in a very long time. I also work for myself, started life as a country kid, and grew up fixing what was broken. Given the complete lack of local technical support and the great distances involved to ship it, I either had to "fix"...

Re: Questioning Pro2 Product Quality - Ongoing Issues

Having read through this thread I guess I can consider myself "lucky" as I have only experienced some of the issues noted. I will not relist the issues, only the solutions I have implemented. 1). Convert the hotends to water cooling. The stock heat sinks are a joke and a fundamental design...

Re: Disable the "Task finished" menu after printing in the latest RaiseTouch

I completely agree. What is the purpose of "Print success" or "print failure"? Wasting our time. Ditto the "Done" menu. Seems totally pointless. What bugs me about the latest raise touch version is that the touch screen is unresponsive after power up and booting for a v...

Re: 'Special' filament problem/questions (wood, metal, carbon, etc.)

Based on my experience for the past 16 months with a Pro 2, it is my opinion that the stock air cooled throat heat sinks are WOEFULLY inadequate. Many filaments get "sticky" before actually melting in the hot end and due to inadequate cooling of the throat tube above the hotend, the filame...

Re: Liquid cooled heat sink for the Pro2

The block is cross drilled so it goes in one side, back, across and forward to the front then out. You can see the gap at the front? That slit goes back to the 6mm hole and allows clamping on to the throat tube, so the water route must be a "U" profile. Extremely effective. Possible that a...

Re: Liquid cooled heat sink for the Pro2

Kenny, I will have to think about this a bit more, but I don't feel it unreasonable to expect some compensation for the time I spent designing, building, and proving the effectiveness of water cooled heatsinks on the Pro 2. The estimated price I noted above does include a modest profit, but given th...

Re: Stop heating unused extruder on Pro2

Yesterday would not be soon enough. I have managed to get filament profiles configured that won't turn on the un-used extruder but it was a time consuming and frustrating process. Shouldn't be so hard.
