Re: 1st time printing ABS - heated bed not reaching 110ºC gets to 105-107ºC - - 9 years ago
I used a cork placemat cut to shape and held onto the bottom of the bed with bulldog clips. I also lay another one on top of the bed while it is heating up - not necessary to reach 110C but it does speed it up.by phyllis_ave - Reprappers

Does the X axis move in the correct direction when jogging manually?by phyllis_ave - General
Re: Big glass jar for ABS-acetone? - 9 years ago
I use a rice cooker for this. You can still see through the glass lid and you don't need to use your heatbed to heat the acetone.by phyllis_ave - General
Re: Oh noooo! - 9 years ago
I'm no expert but I think you need to update the steps per mm/inch in firmware. Try this calculator: http://prusaprinters.org/calculator/by phyllis_ave - Reprappers
Re: Diagnosing THERMAL_RUNAWAY - 10 years ago
The defaults were not suitable for my heated bed either. I think the default is a 2'C drop and I had it faulting nearly every print so I changed to 5'C and no issues since.by phyllis_ave - General
i3 X carriage sagging - 10 years ago
I have a Prusa i3 and my X carriage seems to be sagging. Does anyone else have this problem? I've noticed when trying to level my bed that the hotend nozzle seems to be closer to the bed in the centre and further away on the perimeter. My glass bed is flat and my X axis rods are straight when the carriage isn't on them so it seems like the weight of the X carriage/extruder/stepper is bending theby phyllis_ave - General Mendel Topics
Re: Problem with configuration - 10 years ago
I'm no expert but I don't think there is a way to extract firmware from your board. You'll either need to ask your supplier to send you the pre-configured firmware so you can tweak it, or download the standard Marlin and modify that.by phyllis_ave - General Mendel Topics
Re: prusa i3 gear reduction? - 11 years ago
I think it would be fine, you would just need to change the steps per mm in firmware to suit.by phyllis_ave - General
Re: i3 Build Problems - 11 years ago
Are you using RAMPS? And what sort of computer are you using? I just built the NorCal i3 with RAMPS and a Raspberry Pi and I'm using a lower baud rate 115200 (I think)by phyllis_ave - Reprappers
Re: Octoprint - data usage - 11 years ago
So it looks like this has been addressed on github: However, I've never used linux at all before this and I have no idea how to update the Octoprint install on my RPi. I tried just manually putting that code in the main.js file but that didn't change anything. Do I need to compile/activate it somehow?by phyllis_ave - General
Re: Octoprint - data usage - 11 years ago
Ok so it looks like it is sending the webcam stream whenever you connect to Octoprint, even if you don't have the stream showing. If I disconnect the webcam Octoprint showing the front page (temp graph) it sends around 1kb/s. With the webcam connected but only front page showing it sends around 500kb/s With the webcam connected and showing stream it sends the same 500kb/s I really want to be aby phyllis_ave - General
Re: Octoprint - data usage - 11 years ago
Any ideas on how to reduce the amount of data streamed? If anyone else is using Octoprint to monitor prints remotely have you checked how much data is being sent? I'd like to know if its normal to use so much or if I've just set it up wrong.by phyllis_ave - General
Re: Help! ATX PSU for i3 - 11 years ago
If you disconnect all the wires then touch the green wire to black does the psu start? Also a simple mistake that I have made before - the power switch on the back of the psu in on right?by phyllis_ave - Reprappers
Re: Octoprint - data usage - 11 years ago
I actually started the print, loaded files, etc from my home network. All I did on my phone was check to make sure everything was running okay.by phyllis_ave - General
Octoprint - data usage - 11 years ago
I'm using OctoPrint to control my Prusa i3 throught a Raspberry Pi and everything is working fine except that it seems to be sending heaps of data over the network. I logged on with my iPhone for about 10 minutes and it used over 600Mb. Is this usual behaviour? Is there anyway to reduce this? I did have the stream from the webcam up for about 1 minute but even just the main screen showing the tby phyllis_ave - General
Re: Help with Marlin Configuration - 11 years ago
So I found the problem - the pots were just set too high. I had been starting a move then adjusting the pot on the fly to try and find the best power level. This doesn't work, I needed to stop the motor, then adjust the pot, then issue a new command. A newbie mistake but that's what I am when it comes to 3D printing. All is working now. I'll be trying my first test print tomorrow! Thanks forby phyllis_ave - General

Re: Help with Marlin Configuration - 11 years ago
The RAMPS board came prebuilt - all the jumpers I can see are connected (1/16th step) The motor wires are connected in this order: red, green, yellow, blue - with red closest to the power terminals As far as I can tell the board is wired properly - see photo attached. Does this look correct? I can take some more pics if that's not clear.by phyllis_ave - General
Re: Help with Marlin Configuration - 11 years ago
Thanks for the link - that's exactly what I was after. So I've confingured and uploaded marlin correctly (I think) but the motors aren't working properly. When I test them by sending Gcode they just hum and don't turn. I thought this might be the pots not being set right but no matter where I turn them the motors don't respond. If I have it on the minimum the motor makes a very quiet squeal andby phyllis_ave - General
Help with Marlin Configuration - 11 years ago
Hi All, I've just finished building my Prusa i3 and it's time to get the software/firmware running. I found plenty of guides to help me build the printer but it seems hard to find help on how to setup the firmware. I have the Arduino IDE program and have downloaded Marlin from github but I don't know what I need to change in the code to make it work with my printer. Could someone please point mby phyllis_ave - General
