Re: Z-height sensor - inductive? - 10 years ago
I am not sure of the need to continuously monitor the height. If the need is simply to set the inital zero Z figures before a print start - maybe at the usual four positions - then a combination of the solenoid and the capacitive vernier might suffice. Sensor fixed relative to nozzle - Z difference known. Fire the solenoid to extend the contact tip, and measure the extension. A bit of arithmeticby GregL - Ormerod
Re: What I'm up to with my Ormerod - 10 years ago
This was an early attempt. It needed quite a bit of the grandchildren's modelling clay to get the balance, and consequently flew only a little better than a lead baloon. For amusement, I have attached the scad file. The starred lines produce half a fuselage, one wing and the tailplane. The wing was printed with no infil, but was still too heavy Gregby GregL - Ormerod

A very big vote of thanks to you Steve. I realised today that my blood pressure is much reduced. Gregby GregL - Ormerod
Re: Please get rid of these GIF images - 10 years ago
OK Answered my own question. I entered 'forums.reprap.org/mods/smileys/images/hot.gif' as the name of the custom file - not realising that I then had to open it up and enter it in as an actual filter. Done that, and now those nasty moving GIFs have vanished. Thanks again Steve Gregby GregL - Ormerod
Re: Please get rid of these GIF images - 10 years ago
Steve, Not noticed any change yet. Got the Adblock and Easylist subscriptions engaged, and the forums.reprap... in as a custom file - with its checkbox ticked I notice that Afdblock reports 0 custom files. Hmmmm. What am I doing wrong? Gregby GregL - Ormerod

Re: New firmware 058-dc42 and web interface 0.69 - 10 years ago
I tend to use gcode viewer - its estimate of time to print has proved to be quite good. On another matter: what is the optimum way of updating to web interface 0.69? I am currently running 057y firmware. Gregby GregL - Ormerod

Re: Printing artefacts: cause and remedy? - 10 years ago
Kim, I'm not sure what tools you use to create your STLs, but if you form holes etc by 'taking away' one shape from another, then you may have hit a problem I had with SCAD. When my 'take away' shape only extended to the edge of the object, sometimes it would look OK as a hole, and sometimes it would leave a miniscule layer over the hole. This had a knock on effect when exporting as STL. Solutioby GregL - Ormerod

I'm sure that I will not be the only one who finds the GIF images at best: distracting, and at worst: intensley annoying. Please can we get rid of them? Gregby GregL - Ormerod
Re: Hmmmm Now there's a first...... - 10 years ago
Kim, This has been happening to me too over the last few prints. I found the bearing desperately needed some lubricant (I had been ignoring all the bearings!). The bearing would run OK, but on a change of direction it was inclined to stop and refuse to start moving unless given a good hard push - solved now it is lubricated. I have instituted a permanent fix (not as permanent as super glue!!!) 1by GregL - Ormerod
Re: Best User Upgrades? - 10 years ago
I discovered that the main problem was really lack of lubrication on the bearing. It was decidedly sticky when reversing direction, and that probably overcame the grip from the x-carriage. Bearing nicely moving now after some 'lock lube' - but I also drilled down behind the sensor, and jammed a bit of paper clip in the hole to locate the circlip groove in the bearing. The paper clip portion willby GregL - Ormerod
Re: Best User Upgrades? - 10 years ago
Thanks Les. Looking at the carriage, I am thinking that a solution might be as follows: Drill a pin sized hole vertically down through the bit of the carriage which mounts the sensor board. The hole would break throgh the inner curve of the bearing housing - such that a pin would positively locate in the circlip groove of the bearing. Job done. Gregby GregL - Ormerod
Re: New PSU - 10 years ago
Don't forget that the 20 amp is at mains volts, so we are talking 5kW capacity At 12V that would be in the order of 400 amps!!!by GregL - Ormerod
Re: Best User Upgrades? - 10 years ago
Is there an upgrade for the x-carriage? Recently, my one seems to have lost its grip on the bearing. Several failures resulting from a positive X movement causing the carriage to leave the bearing behind, and the head to crash onto the print. I suspect the carriage has softened/relaxed with the heat. Need some sort of clamp/catch to hold the bearing in place. Gregby GregL - Ormerod
Re: Slier problem - 10 years ago
I deleted that line in the custom code, and sli3er now inserts four lines before the custom code G21 ; set units to millimeters M107 M190 S65 ; wait for bed temperature to be reached M104 S195 ; set temperatureby GregL - Ormerod
Re: Slier problem - 10 years ago
No. It inserted these three lines before the custom code G21 ; set units to millimeters M107 M104 S195 ; set temperature so no M140 S65 was created along with that M104by GregL - Ormerod
Re: Slier problem - 10 years ago
Thanks Dave, Can I just remove that from the custom code? Slicer has already inserted M104 S195 ; set temperature from the filament settings - why didn't it do the M140 as well? When Sli3er gets round to the second layer, it correctly inserts the temps for head (M104) and bed(M140) Gregby GregL - Ormerod

Slier problem - 10 years ago
I have been running Sli3er ORC2 for some time without problem I used the ini files that dc42 produced ages ago. Recently I managed to lose the filament ini file, but quite happily edited what was there to give 65 bed and 195 head for first layer - then 60 and 190 for the rest No matter what I set that first layer bed temperature to in Sli3er, the G code always sets it to 60 'M140 S60; Set bed teby GregL - Ormerod
Re: OpenScad advice... required. - 10 years ago
28 years teaching B.Sc. and M.Sc. Computer Science gave me some practice! When looking at the paraboloid module, I copied and pasted the innermost operation (.3) and ran that - gradually adding the other operations one at a time You have to make sure that any variables used eg hi had to be set up in a separate statement Gregby GregL - Ormerod
Re: OpenScad advice... required. - 10 years ago
QuoteTreth Regarding the execution sequence. So the code is effectively all read in until a semi-colon is reached, hence .1 and .2 are executed. Then all the lines are read in until another semi-colon (at 0.3) is found and code is execute back up the lines.... What happens with the jump from sequence at 0.8 and 0.9? and again with .11 and .12? So as I gradually learn to read and modify code,by GregL - Ormerod
Re: OpenScad advice... required. - 10 years ago
I have annotated the code I used in my earlier post above. It uses the Paraboloid code from elsewhere, with a bit of mycode to call it a couple of times. I show the numbered steps in the order they are performed by OpenScad Steps 1 and 3 call up the paraboloid module, so its numbered steps (.1 to .16) are performed inside the 1 or the 3 I do not pretend to understand what those squares are to dby GregL - Ormerod
Re: OpenScad advice... required. - 10 years ago
This is only my understanding of what goes on The key to the sequence of operations is to clearly focus on every semicolon and curly close bracket. OpenScad will push each operation and its arguments on to a stack (when reading in normal left to right manner) Only when OpenScad discovers a semicolon or curly close does it actually perform the operation on top of the stack - and produce a 2D or 3by GregL - Ormerod
Re: OpenScad advice... required. - 10 years ago
I suspect that OpenSCAD might have some links back to an old AI language called Lisp - it too had a habit of doing things in reverse order. Separate statements ( terminated by ';' or '}' ) are seemingly performed in a normal sequence - However inside the statement, where there are cascaded operations, it starts with the one at the terminator, and works its way backwards towards the beginning of tby GregL - Ormerod
