Re: Diamond Hotend thermal insulation sheet - alternatives - 8 years ago
Seems to be better than my solution. I just got it and haven't got the time to update my entire build with it. My main issue is that brass is not as conductive as aluminium so it takes longer to heat up (also takes longer to cool down for the exact same reason) Side note: I am also working on an adapter for my build and have decided to go with a simpler design. It is a bit cumbersome to put toby MRGiacalone2005 - Mechanics
Re: Help replace dead hotend heater (Ohm's Law and Rated Wattage) - 10 years ago
Thanks for the reference to the PSU set-up. I have a new PSU but don't have time to test it yet. Meanwhile, it turns out that the volts were actually changing but only at the end of the heating. The issue was that #define PID_MAX only comes into effect once it is activated (close to the desired temperature). To test from the beginning of the heating process (from 25 to 200) change #define BANG_Mby MRGiacalone2005 - Controllers
Re: Help replace dead hotend heater (Ohm's Law and Rated Wattage) - 10 years ago
Correction: 225 should be ~23w and ~2amps. Update: I tried with the firmware output at 225 and when I send a print the PSU shuts down again. Took the output in the firmware down to 200 and it works without shutting down the PSU. 200 should be ~20w and ~1.9amps. I will post an update when I connect a different PSU. --------------------------------------------------------------------------------by MRGiacalone2005 - Controllers
Re: Help replace dead hotend heater (Ohm's Law and Rated Wattage) - 10 years ago
From your answers I decided to purchase a 5w 5.6ohms and a 5w 6.8ohms. Those things are way bulkier than the one I had. Side by side I would have never though the smaller one was an 8w (and now I think it wasn't an 8w). I had to attach the 5.6 ohms to the heating block because it does not fit the hole on the block. This means a lot of the heat is going to inevitably go to the air. However, I didby MRGiacalone2005 - Controllers

Help replace dead hotend heater (Ohm's Law and Rated Wattage) - 10 years ago
Dear All, My ceramic heater is dead, which one should I get as replacement? I get a lot of information from reprap and the internet but a couple of things get confusing between reads. Quick Background: Before I killed my heater, I was preparing to heat up to 230 to do first test of extruding ABS. I had already done some heating before without filament and it worked fine but it was not on for loby MRGiacalone2005 - Controllers
Re: Rostock Stepper Motor Problem - Help - 10 years ago
If it is not your board, it is possible that it is a faulty stepper (not a complete loss). If all the steppers are from the same provider and have the same specifications they should all work pretty much with the same current. And changing the drivers should work if it is a faulty driver. However, just to be sure instead of changing the driver and the steppers back and forth, try reducing the curby MRGiacalone2005 - Delta Machines
Re: Repetier Printer Settings: Limited Delta Radius, Motor Runnig Wild? - 10 years ago
You are right, a Circular shape is very fast compared to the triangular shape with rounded corners. But if it was a complete triangle (which is easier than that shape) together with the added limitation of only positive values for the Delta carriages, it would be an almost perfect maximum print area. I also agree, 'most delta beds are either square or circular anyway', but it can be said that thby MRGiacalone2005 - Repetier

Re: Delta Rostock level calibration problem - 10 years ago
hercek: Thanks. It is two of us building it, so we can spend some time in the design (endless hours of arguments and running back and forth to the drawing board won't be missed though). Since we are still in design/building phase, I'll see if I can open a log of our build. (I'll post it with the Delta topics). So far I have only created a Flickr group for anyone to show their best pics. Regardinby MRGiacalone2005 - Delta Machines
Re: Repetier Printer Settings: Limited Delta Radius, Motor Runnig Wild? - 10 years ago
Thanks for clarifying that. As long as we are talking about area shapes it might be more useful to get rid of circular area altogether. We are clear that a quadrilateral area allows for moves that are beyond the reach of the rods, but circular area limits the movements to a very small area compared to the actual maximum reach. If we consider the maximum reach of a Delta having very long arms thiby MRGiacalone2005 - Repetier
Re: Stepper Tilted Axis. - 10 years ago
Thanks for the useful info. That is possible. I'm sure we didn't drop it, and if it was dropped by someone during shipping, I would have guessed that it should have a small dent or something - no sign of that. Still, even without the dent it is possible that it was dropped. Anyway, the supplier agreed to send a new one with the next order. We are still going to set up the machine with the defecby MRGiacalone2005 - Reprappers
Re: Stepper Tilted Axis. - 10 years ago
Good advice. They were sent from Hong Kong though but I'll contact the supplier to see if they will send me a new one in the following order. The subject may still be of importance for some looking for a quick fix, perhaps even one involving printed parts.by MRGiacalone2005 - Reprappers

Quotehercek QuoteMRGiacalone2005 hercek, Great graph. Where did you get it? do you know what function was used?

Re: Delta Rostock level calibration problem - 10 years ago
Quotehercek Maybe you have a combination of diagonal rod length and delta radius error, possibly with incorrect steps per mm. These errors can lead to z-height error like this (these may be at the same height, depending where you measure ABC and centre): If your z-height error is not nicely symmetrical across the 3 axes then position of one of your virtual towers may be wrong too.

I am in the process of setting up a Delta Printer. We just noticed that one of our steppers has a tilted axis causing it to run eccentric (Motors: Tilted Axis). Besides buying a new stepper, does anyone have any ideas of the problems it may cause and how to fix it? Cheers, Marcelo R Gby MRGiacalone2005 - Reprappers
Re: Megatronics V2- Inverted end stop damage IC2 - 10 years ago
Yes that should be a regulator. Maybe that is why I was not able to locate the part. I plugged the mechanical switch in the vcc like an optical end stop because it has a LED on it. Not sure if I'll be using it though. vreihen. You confirm that it was possible to start the board without using a USB.
