Re: Experimental Gen3 Mendel firmware - 13 years ago
New interest in understanding the problems involved in the acceleration algorithms. Im a little confused I thought that 5D uses acceleration algorithms for printing hence its not 3D. I'm Sorry if these are realy Dumb questions. Question One are there problems with these algorithms in:- 1/ The regular reprap Firmware? 2/ The Tonkip variety of Firmware? 3/. The Teacup version of Firmware? 4by BodgeIt - Firmware - experimental, borrowed, and future
Re: Worn out thread x vertical drive nut after 3 months? - 13 years ago
Good reasoning I've just switched over to brass nuts on my stainless bar.. I looked at using 10mm Trapezoidal Spindles for Z axis last year ~10mm was the smallest I could find in the UK. It would mean a re-design of Z drive. The Spindle is expensive & Trapezoidal nuts even more plus a need to change the bearings & gear / motor connection. The Trapezoidal Spindle is about around a £1 pby BodgeIt - General Mendel Topics
Re: Adrian's pololu VS ramps VS gen7 VS ... - 13 years ago
@dissidence Speaking to jmgiacalone from E-Maker at Makerfaire in March I qeestioned his use of fans on his set ups. He said that a fan is needed to keep the 4 pololu drivers from over heating even with the fans I belive he still managed to kill off two of his 4 pololu drivers during the two days of the show. The E-Maker set up was very neat not at all bodged or lasshed up. So I think you shoulby BodgeIt - Controllers
Re: Worn out thread x vertical drive nut after 3 months? - 13 years ago
Even though Stainless steel is more expensive I use stainless steel threaded bar for the Z drive for these reasons:- 1/ Stainless steel threaded bar seems to have a better screw thread than zinc plated steel threaded bar. 2/ Stainless steel seems to always be straight compared to the zink plated threaded bar. For the above reasons using Stainless steel seems to cut out Z wobble As the zby BodgeIt - General Mendel Topics
Re: Big Printer - 13 years ago
I can only asume that Masonite is what we call Hardboard here in the uk. Hardboard in the uk seems to only come in 3mm thick sheets and seems to be structuraly flimsy Bendy. Could Masonite also mean MDF? MDF is avalible in many thickneses 2,3,4,6,9,12mm and is relatively stiff.?by BodgeIt - Reprappers
Re: Windows Repsnaper beta build - Change Requests - 13 years ago
@ Buback 1/ . Im not sure of a method of implementation of the first one as the firmware will have bufferd some of the Gcode. The buffer size is configuable in the Repsnaper set up from 4 to 100 gcodes in the firmware buffer. So this change would need to be implemented on both Firmware and Hostware.. Firmware side needs a control that overides the curent buffer contents so would need toby BodgeIt - RepSnapper
Re: thermal safety - 13 years ago
I think there is also a need for the Host software to be configured as a back up to the Firmware. Thus the host then protects the printer from Firmware failure or hardware failure. Thus the host SW should check curent temp against the target temp for both the bed and Nozzel settings. The host should then take the appropriate action by sending a new target and re-cheking the temp. If that failby BodgeIt - RAMPS Electronics
Re: PC Power Supplies, RAMPS, and Resistor Hot End - 13 years ago
I run every thing on a 30V 12A supply its less bulky than a standard PC supply. I use 6.8ohms 5W @30V with without any problems PCB heated bed is 4ohms again with 30v supply. The FeTS I use are 0.014 ohms RDS on for the Bed and 0.3 ohms RDS on for the extruder so they both have heatsinks.by BodgeIt - RAMPS Electronics
Re: Circles not coming out Circles - 13 years ago
Wow indeed... Wow.. Even with my original home made MDF and fixit block Mendel I achived round circles... it has since been dismantled to steel its motors for use in my other printers. The only problem I found that produced errors was I tried to save heat build up on the steppers by turning them off on X and Y this was a big mistake as it produced an acumulative error on both axis.

Re: Windows Repsnaper beta build - Change Requests - 13 years ago
Dale yep thats a good change request I also have had that happen on the old Repsnaper .. I had forgoten that one. This could also be handled by the firmware sending a message to the host software saying the printer is not ready like all other printing devices ie like an out of paper message or the buffer is full message. Unfortunatly that would mean a change to both the host and firmware... tby BodgeIt - RepSnapper

Re: new version i think - 13 years ago
There is a communication issue or two standards of Temprature reading.. strings The Teslar Tonkip firmware outputs this string for a M105 gcode.

Minimum length of thermal insulator? - 13 years ago
Looking at drawings of the thermal insulator, is 20mm the absolute minimum insulation distance on an extruder? Is there a way to calculate the expected temprature diffrence. I.E if this length was to be 15mm instead of 20mm or 10mm? Is anyone using an insulator with less than 20mm of insulation? The 20mm dimention is based on this drawaing (35mm - 15mm = 20mm) from the hot extruder to the endby BodgeIt - Plastic Extruder Working Group
