Re: X axis sensor - G31 returns zero - 10 years ago
Quotedc42Ian, I think you need to either supply faster SD cards, or change the firmware to allow the SD card more startup time. I've already passed that suggestion on to the firmware team! I'm fed up of apologising for the stupid things... Ian RepRapPro tech supportby reprappro - Ormerod

If you break it, I'll send you a new one! I wasn't involved much in the choice of the resistors, but I know it's a fine balance. I think you've had a bit of experience with these, so I'll leave you to it; any feedback would be greatly appreciated. Ian RepRapPro tech supportby reprappro - Ormerod
Re: x axis carriage 9mm bearing not free - 10 years ago
Hmm.. I've checked mine, and the washer does seem to interfere with the MR93ZZ bearing; but I have to over-tighten the screw to do it. Turning the (slightly dished) M3 washer over makes it better, and moves fine at 'normal' tightness (no, I don't have torque settings...). I swapped in a 623 bearing, which seems to rotate fine when tightened hard, but doesn't give you much adjustment for the angleby reprappro - Ormerod
Re: re-designed z-axis mount - 10 years ago
The z-nut-trap printed part now hold the ... er... z nut trap! It's no longer in the x-rib, just in the printed part. You can compare the old and new z-nut-traps; github lets you go back into the history: Old one: New one: The original x-rib had four potential failure points: 1.

Re: re-designed z-axis mount - 10 years ago
The colour is the same as the red filament we sell, of course! We generally expect people to print updated parts for themselves - the printer will work with the parts supplied (with the odd work around...). We weren't planning on printing red z-runner-mounts - we can send you a green one, if you want. We are printing some of the updated z-nut-traps in red, for RS customers, mainly because x-riby reprappro - Ormerod

Re: Fan backwash causes warping? - 10 years ago
@Rory: The filament threads between protrusions is usually a result of printing a little too hot, and fine tuning the retraction speed and distance. It can usually be tuned out. Filament can have quite widely vary properties; particularly from different manufacturers, and different colours. It's something you have to experiment with. @dc42: We increased the size of the fan (from 40mm x 40mm x 10by reprappro - Ormerod

The Think3DPrint3D boards are produced by the same company that we get them from, and uses the same firmware. They even have the same sticker on the ARM chip that we get!

Re: What is RepRappro policy on self-repair of Duet boards? - 10 years ago
It's an interesting point, dc42, and something we've been mulling over, especially since we went 'big time' with RS! Our general policy is that it is your printer, and you are free to do what you want to it. It's the nature of machine evolution that Adrian Bowyer promotes, that by Open Sourcing the design, people are free to make their own choices, and the printer can develop independently of usby reprappro - Ormerod
Re: Repositioning the Z axis on the X axis bed. - 10 years ago
Hi Rory166 The instructions have changed substantially over time, and are continuing to evolve. We do plan to do a pdf version for printing, but only when the instructions are more stable, and I advise people to use the online version for this reason.

Re: Motors not running - 10 years ago
chriscain - excellent! Good diagnosis skills. Glad you were able to get it working. Was the hub independently powered from the mains, or was it powered from the computer USB port? We've found if they are not powered from the mains, the voltage can be on the low side. 3 different voltages are used on the board: 12V for motors, fans and heaters, 5V is used to drive the MOSFETs, and most other partby reprappro - Ormerod

I think it will help to use our profiles; Adrian has written these so the start gcode is correct. I think you are using the Slic3r defaults, which may give poor results.

Re: Bed levelling glass build surface only? - 11 years ago
The foil is ON TOP of the glass, in the corners, but under Kapton.

Re: Extruder problem - 11 years ago
Hi Danie If you set the motor to extrude 100mm, then hold the large gear, does it feel like it has too little strength? It does sound possibly like a motor or motor driver problem, though could be wiring. The vref is set in firmware, and should be correct. Can you try swapping the motor from another axis, and reseating all wiring? That should rule out the motors and wiring, and whether it's a bby reprappro - Ormerod

Re: X/Y Axis movement - 11 years ago
Sorry, my mistake... The Y axis homing switch is a MAX endstop. ie it triggers at the maximum positive point. So when the Y axis homes, it finds it's Y=200 point. Then it can move back to 0, at the other end of the axis. Without this, due to the orientation of the Y axis, any part printed would be mirrored. The other two axes are MIN endstops; they trigger at 0 for X and Y. Also, orientate theby reprappro - Ormerod
Re: Ormerod from RS - 11 years ago
Treth Re Kapton tape over the aluminium foil - the IR beam has no problem passing through the Kapton. It's the glass (more reflection/refratction), and the distance to the aluminium under the glass (greater than 3mm) that causes the problem. If you're homing directly onto the aluminium without the glass, I would guess that it won't have any problem. But then you're going to have problems printinby reprappro - Ormerod

Re: Ormerod commissioning/ bed leveling - 11 years ago
Hi Markus The picture in the comissioning instructions is Adrian Bowyer's development machine. He likes to manually adjust the bed so it's close to level; however, we don't supply the longer screws and extra nuts to do it this way - it should be an unnecessary step with the auto compensation! The bed shouldn't be that far out of level with the X axis as built. I'll update the instructions, whenby reprappro - Ormerod
Re: X/Y Axis movement - 11 years ago
Daniedb It depends what you are describing moving. The Y axis + and - in your picture shows the nozzle movement relative to the bed, rather than the actual movement of the axis, which is the other way! The motor end is the homing position of both X, Y and Z axis. At 0,0,0 the nozzle should be over the back right hand corner of the bed, just touching the surface.

@mandeng The thickness of the acrylic shouldn't be an issue, so long as it is a linear change along it's length, and neither should the angle of the arm. The whole point of changing the electronics and firmware is to allow for compensation of ALL of the axes. That is, you measure the deviation from straight, and the firmware compensates for it.
