Sorry I may have mislead. Most of the people in the forum are very helpful & friendly. The reason there is a bit of an issue with posting your version information is that some people use daily updates and it makes it very hard work for those supporting to help without the version information. The first sticky post in the forum tells you how to post your info http://forum.freecadweb.org/viewby KeithSloan - 3D Design tools
Suggest you post in the FreeCAD forum Just remember to post your FreeCAD version information, otherwise some of the moderators might biteby KeithSloan - 3D Design tools

When I just checked you have funding of $6460 out of a target of $42,000 with only 55 hours to go. Seems to me that there is a good chance you will miss your funding but fingers crossed for a late surge. Do you have any plans for if you don't make funding? I guess its not so easy to get people to sponsor when the final deliverable is Open Source i.e. free so getting sponsors requires people whby KeithSloan - 3D Design tools
My understanding is that scratch is implemented in squeak ( a version of smalltalk) Is BlocksCAD also implemented in squeak? I suspect not as your solution is web based. It mentions that a desktop version will be made available if a funding goal is reached. What Desktop? Windows, Linux, Mac. What language is BlocksCAD implemented in?by KeithSloan - 3D Design tools

Quoteneildarlow The rods need degreasing otherwise they will slip in the clamps. Remember to degrease them again after sliding them through bearings. So should one just degrease at the ends i.e. where the clamps are. Or the whole length. Does the grease not help with going through the bearingsby KeithSloan - Mendel90
I have degreased the motor shafts as per the instructions. Does one just leave the steel rods as shipped or should these also be degreased? I assume not, but just want to be sure.by KeithSloan - Mendel90
For those frustrated importing OpenSCAD files to FreeCAD by lack of support for hull & minkowski functions, there is the opportunity try a new beta test version of FreeCAD's OpenSCAD module see http://www.sloan-home.co.uk/ImportCSG/ImportCSG.htmlby KeithSloan - Mendel90

I brought my Mendel90 kit quite some time ago and had to put its construction on hold for a couple of reasons. Anyway I spent the afternoon putting the Extruder together and would like clarification on page 50 number 9. Which ends "Tighten them until the end of the screw is flush with the back of the bearing." Not sure what it means by back of bearing? Does it mean level with the rounded end ofby KeithSloan - Mendel90

If you have been following the discussion in the FreeCAD forum. You will see that there is a license conflict between Open Cascade that FreeCAD uses and GCAL as used by OpenSCAD for the hull operation.. The other problem is that a Hull operation would produce a polygon, which if it was extruded would create a Mesh. In which case would you be any worse off than with an imported STL file which wby KeithSloan - Mendel90

Thanks yes Hull is not supported. I have just completed an Open University exam, Monday, with that now out of the way my new priority is to complete my Mendel90 which I started but had to put on hold. But I will have a look again at what is involved with adding support for Hull, but I suspect its far from trivial.by KeithSloan - Mendel90
I assume you are loading the scad files into FreeCAD. Did you do them individually? or as one whole file? I would be interested to know which individual files failed as I am always looking for test cases for ImportCSG as used by FreeCAD in the process of loading scad files.by KeithSloan - Mendel90
Well if I load the original SCAD file in OpenSCAD and create an STL file it has holes. If I load the file in FreeCAD and export an STL it has holes. Not sure why Blender should cover the holes. I guess if it slices okay it does not matter. Wonder what happens if somebody tries a different slicer than Cura. I am still building my Mendel90 and thought the modified spool holder would be a good thiby KeithSloan - Mendel90
When I open M90spoolholderNew1Rotated.stl in FreeCAD or Netfabb Studio Basic the three holes just show up as lines and not as holes. What did I do wrong? Is this a coincident faces problem, i.e. the holes in OpenSCAD should go all the way through and a bit beyond. Least it looks that way when I load the original file in OpenSCAD I loaded the original scad file in FreeCAD and the holes are therby KeithSloan - Mendel90

A good source of info on the Pi's GPIO is mung as to "Have you ever tried using resistors?" Your not going to drive 5 volt logic from 3.3v signals with just resistors. You need to learn some basic electronics. Although is also has the same challenge of 3.3v logic, I would have thought a BeagleBone Black ( BBB ) would be a better solution than the raspberry pi as it has more GPIO supports ADC sby KeithSloan - General
