Re: Belt Tensioner , do you recommend ? - 6 years ago

Thanks Guys for the advice, much appreciate. I decide not to use the spring method , just a bolt tensioner that pulls the belt tight & make sure it stays like that. Its been working fine and good results from my prints.

Re: Heated Bed Thermistor reading far too high - 6 years ago

Thanks guys for all the help. I selected the 10K thermistor & its reading the room temperature correct. I run a PID and entered the figures into marlin etc. Seems to be working fine. I would not know if my Temp on the BED is perfectly 90 when I do a print but it seems to be working. Thanks for all the help

Belt Tensioner , do you recommend ? - 6 years ago

Hi Guys I have a heated bed that's 400x400 running on two 20x20 Extrusions with wheels. My question is I see some people add a Belt tensioner. ( The cloths peg type tensioner ). Would you recommend it. The belt from the stepper motor to the bearing ( Nut Tension ) to tighten up the belt is pretty long. So wondering if you add the wire tensioner in the middle of the belt would be beneficial.

Re: Heated Bed Thermistor reading far too high - 7 years ago

Hi The packaging etc says it a 100K NTC thermistor . I set the multimeter to 200K because my multimeter does not have a 100K point. My room temp is about 28 degrees . The reading on the multimeter is 6.8 ?

Heated Bed Thermistor reading far too high - 7 years ago

Hi Please could you advise, solution I have installed a Silicon Heated 300x300 230V AC 300w with a SSR solid state relay. ( 25A ) Specs on silicon bed is 100K NTC 1% thermistor. In marlin ( 1.1.6 ) I have tried Thermistor no. 1 & 6 & 75 but they all read 90 degrees yet it suppose to be around 28 degrees ( Cold bed ) I plugged in a spare thermistor and reading was correct 28 Degrees (

Re: Please help, strange movement while printing - 7 years ago

Hi Roberts, You are super hero , thanks so much. I notice there was plenty of garbage on my LCD screen & just left. Now I realize that you say its the SD card problem. When I print from the laptop it does not happen. Cool, I find a way I can move the cables away from the wires of the step motors . They all bunched up in one box at the moment. So that's a No No. Thanks a Ton. Vaughan

Please help, strange movement while printing - 7 years ago

Hi everyone, Using Ramps 1.4 board / Prusa style printer ( Marlin 1.1.6 ). Printer has been printing fine, now suddenly while printing the head moves away from the model ( No extrusion ) and then comes back & carries on printing. It does it on both X & Y direction. This happens every now & again. It does not extrude when it moves away. What could it be causing the printer head to mo

Thermal runaway - 7 years ago

Hi Please can you give me some advice. I have upgraded my marlin firmware to the latest version and now I get a Thermal Runaway error as soon as the Bed fan comes on after the 1st layer. I have done PID tune on the hotend , but still get the Thermal run away error with the new settings. Any advice would be appreciated thanks Vaughan

Re: Bed Fan only on at 100% - 7 years ago

Hi Thanks, stupid question , how do I reduce the Hz ? Where is this setting, is it in Marlin Firmware ? Thanks

Re: Bed Fan only on at 100% - 7 years ago

Hi I have the Fan plugged into the Ramps Board where the heated bed fan usually is. I need to try another fan and see if does the same thing. Just strange that when I try reduce power , it switches off . Runs only if its at 100 %. Thanks anyway for your time & replies.

Hi Please can you tell me where the firmware resides ( Marlin ) when you upload to the Arduino Mega & Ramps 1.4 ? Does it sit on the Arduino board or the Ramps 1.4 board ? Thanks Vaughan

Printer slight pause during prints - 7 years ago

Hi Guys While my print is printing the printer will do a slight ( 2 second ) pause and carry printing. It seems to happen when it move to other parts of the print. I have changed & bought a new USB cable & also happens when printing with the SD card. Please could you try point me into the right direction. Very frustrating to see the pause. Happens with all my slicers Thanks Vaughan

Re: Slight Pause in my Printing - 7 years ago

Hi I changed the USB cable and it did the same thing. I then changed from Simplify3D to Slic3r and there is no pause in the print. So it must be the slicer program - Simplify 3D Any suggestions Thanks

Slight Pause in my Printing - 7 years ago

Hi Guys I have upgraded my firmware to the latest Marlin firmware to my Prusa i3. While printing there is a slight ( split second ) pause to my printing. I have changed the Jerk from 20.00 down to 5.00 and no change. Not sure whats causing the printing to do that slight pause during my prints. It seems to be when it changes LINES, not even when it increases height. I tried printing from SDcard

Re: Folger FT-5 or HyperCube and bed with one side support - 7 years ago

Hi Thanks guys I really appreciate your comments and advice. I thinking maybe reduce the height to 300mm and increase the frame from 30x30mm to something like 40x40mm extrusions. After reading a couple of threads , I am not sure which way to go on the style of printer ( CoreXY) . I have build two printers from scratch ( Mendel90 & Prusa i3 ) . I am not too concerned about speed of printing,

Folger FT-5 or HyperCube and bed with one side support - 7 years ago

Hi Guys I am wanting to build either one of these printers , at least I would like to build a CoreXY printer. ( Build volume X400 Y 300 Z 400 ) with 30x30MM aluminium extrusions. Which out of the two do you prefer and reasons ? The other question is , do you think its important to have the bed supported on both sides ( two or one Z Stepper motor ). I see some have only on the one side. Wonde

Hi Guys, Please can you tell me if I am able to change % Infill while your printer is printing ? I know you can make the changes before you start the print, however what code do you use to make the change from 10% to 20% while the printer is printing. Thanks, appreciate the help.
