Re: Ebay SINTRON Kossel Mini full kit - 10 years ago
I dont understand how it can be my extruder motor. I have not had this problem before. It only occured after I finished printing the 5 to 6hr print. After that all of my other prints with PLA have looked like that picture. If I do the print for say 3hrs. It will have bands. Starts off good. Then under extrusion. The good. Then finishes with under extrusion. How do I check the current in config?by DRTak - Delta Machines
Re: Ebay SINTRON Kossel Mini full kit - 10 years ago
Need help. I was printing a large file. 6hrs long. It printed fine in PLA. But now when I go to print anything it prints like below? The bottom is perfect so to speak. But I would say 30min into any print, the top part gets choppy like the picture and see through? I dont understand. I can only assume the nozzle is clogged or partially clogged. But I checked the flow and it looks great. I am at aby DRTak - Delta Machines

They have them in protein shake jugs, candy, etc. I put like 10-20 packs of those in an "air" tight tupper ware bowl and toss in the spool of PLA/ PETG.

Quotehacker QuoteDRTak With PETG and PLA my spools are contained in dessicant. However, I didnt use dessicant when I first started and PLA was very brittle before and after a print.

Re: Ebay SINTRON Kossel Mini full kit - 10 years ago
Ok. I see your argument for PLA warping or not. I do not have experience with nylon. My assessment is based on the melting point of nylon. I also I have only read about nylon's issues with humidity and water absorption. No experience with it personally. I dont want to pay the extra for nylon bridge. I have read my reviews and PETG and nylon bridge are comparible. Both are somewhat flexible. Buby DRTak - Delta Machines

QuoteJamesK QuoteDRTak How did you verify that your thermistor was the correct temp? I cannot figure out how? Do you aim the IR thermometer at the heatbreak? I compared the thermistor readings against the K-type thermometer. I'm assuming that the K-type performs according to spec, which may be a bit of a leap, but what can you do. The hotend is too small to get reliable readings with the IR therby DRTak - Printing
Hexagon Hotend with Kossel Mini Review - 10 years ago
My original Sintron Kossel hotend aluminum heater block broke. So instead of replacing it I bought a new different hotend. I searched the net and looked for a unique one. ie Not E3D I opted for the Hexagon Hotend. Its all metal and has a unique heatsink. Its the heatsink and the connection of the heatbreak tube to the heatsink that is different. It connects to the aluminum heaterblock the same asby DRTak - Delta Machines
Re: Ebay SINTRON Kossel Mini full kit - 10 years ago
Quotehacker QuoteDRTak Well either way, the plain fact in my usage is that ABS warps from heat creep of the heatsink. PETG does not. I assume at a higher temp. Maybe beyond 260 deg C that PETG would start to warp. This plain fact is what I was aiming at, because I was under impression that printed effector is no good, not ABS effector. You didn't really say that. Now I have some picture… I undeby DRTak - Delta Machines
Re: Ebay SINTRON Kossel Mini full kit - 10 years ago
Quotehacker Quoteo_lampe Quotehacker Quoteo_lampe Warping parts made of ABS is related rather to a bigger expansion coefficient than melting temp differences ( compared to PETG.) Yeah, thought of that too. Are you dead sure or do you hypothesize? It's a known fact that ABS has a high expansion coefficient. That's why we put ( heated ) enclosures around the printer to keep the temp difference asby DRTak - Delta Machines

Quotehacker QuoteDRTak Quotehacker QuoteDRTak Your PETG effector should have been better than the ABS one? It has a higher melting point? Well as I said. The heat from my heatsink crept up and melted my ABS effector. The only issue I have with my metal effector is that it is not forgiving when you have a homing error.

So today I realize why peoples PETG does not stick to the glass plate. I bought a new hotend with a new different thermistor. I have no way of testing the settings for the thermistor. Its supposed to be a EPCOS 100K generic thermistor. But I do not know if its a 1k or 4.7k pullup. After various testing, I could not get the filament to stick to the bed.
