Did not know exactly how to title this so came up with "Part Time Manual Bed Leveling" I have Bi-linear bed leveling setup in my Marlin firmware 1.1.7. But thought to myself can I Once in a blue moon decide to do a Manual Bed leveling onto a Borosilicate Glass Plate. Now the reason behind this is the Borosilicate Glass Plate is 3mm thick and my Proximity Sensor has a 3mm range. I would like toby Roberts_Clif - Firmware - Marlin
? Does this controller have a previous firmware loaded. If so then you should be able to see if the controller is communicating. Arduino IDE 1.8.7 is telling you that it can not find the Controller PCB Com Port. Try Plugging in the Controller wait a few seconds. Selecting the Tools menu Tab (Click) Select Port menu (Click) Then select the new Com Port (Click) After Selecting the Tools menu Tby Roberts_Clif - Firmware - Marlin
Using Arduino 1.8.7 IDE and Installing the U8glib And downloaded a Clean Marlin 1.1.9 I found that if #define X_PROBE_OFFSET_FROM_EXTRUDER 29 and #define MIN_PROBE_EDGE 10 Are correct then in order to compile You will need to change the line below to #define LEFT_PROBE_BED_POSITION (MIN_PROBE_EDGE +29) Will get you a clean compile.by Roberts_Clif - Firmware - Marlin
Quoteimqqmi If a full rotation of the 20 teeth pulley covers 40mm, ie 20 teeth at 2mm per tooth, the number of steps a 1.8 degree per step stepper motor needs to do for 1mm is 200 steps per full rotation / 40mm per rotation= 5 steps per mm. so a single full step covers 1/5 = 0.2mm. I understood this but could you explain the 2x and 4x microstepping or point me to where I could read more about 2xby Roberts_Clif - General

If you are simply changing the Mechanical end-stop switch for a proximity sensor then just mount it in a location that is out of the way and plug it in. My Hictop SN04-N mounted on the rear of the X-Axis bearings, and has a thumb screw to fine tune the nozzle's height. The changes to your firmware will depend on the location you place the SN04-N Proximity sensor. Can you show a image of the lby Roberts_Clif - General
QuoteVDX ... with some switching PSU's the "GND"-potential could be up to some ten to hundred volts different, if grounded and connected together or to other PSU's!! Thank You Victor; I had the same thing happen to my 3D Printer. Only when I plugged the 3D Printer into the USB port my Computer would short and reboot, I believe this was caused this voltage difference. Luckily I only lost the 3.by Roberts_Clif - Printing
Is the part that is 3mm off on the screw holes a 3D Printed part. If so it maybe possible you could drill new holes without damaging it. Could you post a picture of the Parts or link to a picture that will not line up correctly. A picture may make it easier to determine if it is possible to re-drill the holes.by Roberts_Clif - Prusa i3 and variants
I would have though that they would fit together without re-drilling. As the Folger Prusa i3 kits are also made with a precision CNC machine. How far off is the screw alignment ?by Roberts_Clif - Prusa i3 and variants
This is entirely possible, though I believe Dust is correct and it is just a back-light problem. More information hereby Roberts_Clif - Firmware - Marlin

I would also measure the Voltage at The Power Supply again at the controller. If you have a voltage drop on the controller then wiring is in-sufficient for the 3D Printer. If voltage is the same then try display contrast control on the back of the RepRap display PCB.by Roberts_Clif - Firmware - mainstream and related support
Never ever thought about buying anything there, Now have more reasons not, Monopolies are killing good business and quality products. Have made most purchases on E-Bay have very seldom met with a bad deal. Of course do not purchase from anyone that has a lot of negative feedback, and E-Bay Buyer Protection Program has always made that seldom bad deal good again!by Roberts_Clif - For Sale

CAUTION is Indeed needed when working with the ramps controllers. I do not have a Ramps though it is ramps compatible, I had an open trace on the circuit board that had to be repaired.

QuoteMermarinc I think formula may be extrusion width multiply layer height multiply print speed. According the this web site that is correct. Calculated from maximum volumetric speed in mm3 per second Printing at 76 mm/s, with extrusion width of 0.44 mm and a 0.28mm layers height, your volumetric speed would be 76 * 0.44 * 0.28 = 9.3632 mm3/sby Roberts_Clif - General
A Couple questions First. Have you measured the 24V supply while the hot-end was heating? There have been occasions when the power supply has failed or became weak. Have you checked the temperature of the controller mosfet hot-end drivers. On my 3D Printers it was becoming very hot so I added a Heat-sink and fan to cool. Are you heating both the Hot-end and the Hot-Bed at the same time? Heat theby Roberts_Clif - General
