Re: Ebay SINTRON Kossel Mini full kit - 10 years ago
I decided to print a duet case and for some reason the edges are curved. So its not an exact square. I have attached pictures. This did not occur when I printed my RAMPS box? Any ideas.by DRTak - Delta Machines

Re: Ebay SINTRON Kossel Mini full kit - 10 years ago
QuoteMrPCatt good point actually.... does anybody have a good cooling solution for our kits (and hotends) ? Most solutions I found either are made for different heatsink diameters or are to big overall costing way to much printspace on the edges. Or both And does it matter having a fan blowing to the noozle? Or do I have to make sure only have the fan hitting the object itself? This is an exactby DRTak - Delta Machines
Re: Ebay SINTRON Kossel Mini full kit - 10 years ago
QuoteTha_Reaper QuoteDRTak DO NOT put the RAMPS below the heatbed. I did that and I fried my MOSFET. Why? Because you cannot see the fan moving and blowing air. Yes I installed a fan below the heatbed blowing onto my RAMPS. It looks amazing. All electronics hidden. But you cannot see or hear if the fan is on. If for some reason the fan is off.

QuoteGrAndAG Today I did very first print. It works! Here it is the 1x1x1cm test cube: The bottom layer is a bit junky because the filament was just inserted and the extrusion was not started at very beginning. But why the corners are round a bit? Is it normal? And it seems it over-extruded (but I calibrated extruder precisely: 100mm requested - 100mm got). The settings was: PLA @ 200C, layerby DRTak - Delta Machines

Quotedc42 QuoteDRTak So If I upgrade to a duet then I have to buy your Panel DUE to get LCD function right? Currently the only LCD supported by RepRapFirmware is the PanelDue.

Re: Ebay SINTRON Kossel Mini full kit - 10 years ago
Heat hotend to 190 ish for PLA. Then you can manually push filament through to see if it works. The lcd screen has a panic switch which u can use to kill the process. I use this all the time To replace filament. Heat hotend. Manually pull out old filament once hotend is up to the correct temp. and replace with different color.

So If I dont use an Arduino Ramps. How do I use my Kossel? What other system can run it. I already changed from Pronterface to Repetier software wise. But the pre made Marlin firmware with Arduino works. I asked James from Sintron what other system I could use and he didnt respond? If there was a more reliable system I would gladly use it.

Re: Ebay SINTRON Kossel Mini full kit - 10 years ago
I think the PSU has just enough power. When I power my heatbed and hotend it takes a bit of time for ABS. But for PLA its fine. I ran into a big problem today. My RAMPs got fried. I tried using NO PC just the LCD. It was fine the other day when it was really cold 44 deg in the garage. But today it heated up a bit and I forgot that without a Laptop to run the Kossel you have to manually turn on tby DRTak - Delta Machines

Quotedc42 You don't need to change Marlin at all to use the IR probe. Use the same firmware configuration that you would use for a normally closed microswitch, i.e. active high signal and pullup resistor enabled. See the instructions I linked to earlier for what bed surfaces do and don't work with the IR sensor. Ok. Im very interested but I have a silly question.

Re: Ebay SINTRON Kossel Mini full kit - 10 years ago
Quotenebbian DrTak, I've found that the most reliable way to calibrate the output size is to measure your diagonal rods as precisely as you can. You need to measure from the centre of the round ball to the centre of the other round ball. Plug that number in, and then calibrate the smooth rod offset so that you get a flat print surface. Then you're DONE with adjusting those measurements. No mby DRTak - Delta Machines
