Quoteo_lampe Who needs ABS anymore? PETG is just slightly better then PLA and still inferior to ABS in terms of heat resistance.by MPower - General
eSun PETG seems a little bit stringy and kinda brittle, at least compared to other vendors. However, the stringiness is minor, just occasional hair lines when the printed object has 2 separate areas and the hotend has to travel in between. Never had to heat the bed up to 100+ degrees. I usually print small parts with no heated bed (room temperature) and larger parts at 50-60 (as a just in case mby MPower - General
Steps/mm for 1.5mm pitch and 1/8 microstepping is 1066.6666, not 1110.8333, like you configured Z. Threaded rods are a poor choice in terms of accuracy, repeatability and backlash. Your maximum feed is probably under 600 mm/min, not 1406.4. Most Chinese TB6560 boards are usually very dodgy, lots of noise causing incorrect stepper positioning. There are some mods to add filters to reduce this issuby MPower - CNC Routers, Mills, and Hybrid RepRapping
Another thing (not going to open another thread for this other one): I suggested the dialogs to have ESC key binded to the Cancel/Close button of that dialog. You agreed and you implemented this, but "Copy object(s)" dialog was left out. It could use the same effect, ESC key closing it. PS: yes, I know, they are tiny bits, probably more important aspects to address on the list. But I am using Reby MPower - Repetier
You set your point of view and zoom level as desired. Whenever you add an object, the software changes these settings without the intent of the user, forcing the user to re-adjust and fiddle with the zoom level. Add 5 or even 10 objects and you will get my drift. Also, Repetier-host is a printer host, you are more interested in the overall view and how objects are arranged on your printing surfacby MPower - Repetier
Is there any way to disable the auto-zoom on object after adding an object? It is annoying to zoom out every time you add an object. Actually, not sure how this auto zoom is even helpful.by MPower - Repetier

That is still doable with regular RepRap electronics, as they have control for at least 4 axis. If you are using Marlin, the axis will be called XYZE. All four of them can perform motions independent of each other. For instance: G1 X100 Y100 Z100 E100 G1 X90 Y240 Z120 E15 In the example above, they moved in different directions and by different amounts.by MPower - CNC Routers, Mills, and Hybrid RepRapping
According to your post, you actually have two axis: X and Y, that you mirror to an extra Z and A. By "mirror" one would understand that the motors perform the exact motion as on the other side. Since XZ and YA pairs perform the exact same motion, you can connect them to the same driver to keep them synchronized (or breakout the step/dir signals to an extra driver). A photo of the machine will prby MPower - CNC Routers, Mills, and Hybrid RepRapping
Not sure I understood the question, but all axis XYZE are independent, as in one axis can be moved in any direction and by any amount, independent of the other 3 axis.by MPower - CNC Routers, Mills, and Hybrid RepRapping
In some countries even laser pointers are forbidden. But I guess it's not the case of Netherlands, just some minor delay probably. After all there are far more things legal thereby MPower - Laser Cutter Working Group
Wouldn't analogWrite() work? Such as: analogWrite(SomePin, Voltage * 255 / 5); if you want to set it by voltage value, or analogWrite(SomePin, Percent * 255 / 100); if you want to set it by power percent value, considering 5V (255 full duty cycle) as 100% power.by MPower - Laser Cutter Working Group
I guess no one wants to pay 1k GBP for a tiny millby MPower - CNC Routers, Mills, and Hybrid RepRapping
Yes, there is always the DIY factor. And pre-owning a 3D printer already gets you the positioning system ready. However, I find the prices for diodes kinda ridiculous. To be more specific, you would expect that at the technology state of 2014-2015 a tiny 2W diode would cost way less then 300 EURO. That also applies for the driver - after you receive it, try to look up the costs for the componentsby MPower - Laser Cutter Working Group
If you want a mill that you will actually use, you should forget about the round column type and go for the dovetail column type. You might also be interested in a belt driven spindle instead of gear, being more silent and being easier to maintain. Proxxon MF70 is _very_ small. If you deduct the 2 x cutter diameter + a bit of clearance, there is not much left Y wise. Quality is no better then anby MPower - CNC Routers, Mills, and Hybrid RepRapping
I was comparing the cost with the cheap 40W CO2 Chinese lasers. They seem to go around 700 EURO and change in Europe, so you don't have to wait for shipping and then pay custom fees. Most of us already have the printer and we just need to swap the hotend with the diode, so it actually is not a big investment. But then again, it's a 2W diode against 40W CO2.

MendelMax 1.0, 1.5 and 1.5+ are 200x200 MendelMax 2.0 is 245x315 For their release date you could just use the Thingiverse posting date. I would remove the estimated cost column; cost depends on the quality of the item, your location for the shipping, etc. Same for printed parts, not sure how it helps. Instead you should rather add the designer URL, be it the official website if any, or Thingiveby MPower - General
Just curious, but what is the estimated cost of the complete machine in your case? And by complete I mean everything, including tiny little aspects such as cooling, smoke filtering, etc.by MPower - Laser Cutter Working Group
Definitely not percent/10 as it goes to 12. The column is probably that "O.D.", whatever OD means Later edit: oh yeah, optical density. so you are fine with 5 at 445nm using around 1W.by MPower - Laser Cutter Working Group
Does this 1.6W one cut the same types of materials as the 2W and 3W, but in more passes? You can also use cat goggles:by MPower - Laser Cutter Working Group

Quotecozmicray??? Where can you buy a CO2 laser rig (with optics, mirrors) for $335??? My remark was for the $500 that Ohmarinus estimated. A random example of CO2 close to that price: Of course, you can probably find it cheaper on taobao or if you dig further.by MPower - Laser Cutter Working Group
That is why I opened the other thread regarding seeing the diodes in action. It's a lot of money, considering it gets close to a small CO2 laser and it should help seeing some cuts before spending. The price is probably ok for the US, but once you add the shipping cost and custom fees, it stacks up pretty high. Diodes are kinda limited in materials they cut, so it would probably be harder to recby MPower - Laser Cutter Working Group
It would be interesting to see actual results from people who bought laser diodes and drivers and actual photos with materials that they managed to cut with those diodes. Something like: diode/driver/lens buying source and photos with various cuts with those specific diodes.by MPower - Laser Cutter Working Group
The thing is I never seen any of the common 2W diodes being sold with a Peltier. At most I saw them with some heatsink or maybe a heatsink and cooler on it. That is why I am amazed they would start degrading at only 30C. Even so, a torrid summer day exceeds 35C, that would mean they degrade without even cutting.by MPower - Laser Cutter Working Group
Is it even possible to prevent it from going over 30C, when it is operating in a room with a 24C temperature? Maybe a Peltier pad attached to the heatsink.by MPower - Laser Cutter Working Group
QuoteVDX ... and the NTC/thermal protection is to shut down the driver, when the diode starts overheating (>30degC) The diode should not be powered when its temperature is over 30C? If the ambient temperature is around 24C, you would only have 6C left until shutdown.by MPower - Laser Cutter Working Group
