Raise3D Pro2 initial impression

Postby Ben Roj » Sat May 19, 2018 8:50 am

I believe many of the forum members have questions about Raise3D Pro2.

I just received Pro2 and will like to share my initial opinion on this new machine.

+
1) the machine build is as rigid as N2, nothing change on this aspect.
2) the Z movement is more quiet than previous N2
3) the aluminum build plate can withstand abuse and heat bed get very hot even at 60c
4) the front and side panel are hold by magnet
5) the touchscreen is more responsive
6) print much faster than N2 but compare to other 3D printers, I think they are the same .

-
1) dont like bed distance adjustment procedure
2) filament monitor can only catch when filament run out but not when clogged
3) the dual nozzle with silicon sockets are very tight against each another, not sure if it will have any long term wear out when they have to rub with one another.
4) fans noise is quite high (replace with noctual fan should fix it)
5) like in another topic, even when print with 1 nozzle the start sequence require to preheat both nozzle so it takes longer time to start the print job.

Thanks for those pictures. They really help folks like me better understand the Pr2 series. Just curious, and I know this is an ask that requires effort you might not be willing, to understand how they mounted the new XYZ stepper drivers in the base as nobody has seen them yet. That might require turning the entire printer on the side to take those photos (I would use a soft towel on the floor) and so again, totally understand if you would not do that.
Also, out of curiosity, are the XYZ axis steppers always locked? In other words, when you just turn the machine on without making any movements, can the extruder head be moved in XY by hand? The reason behind that question, there are 5 position sockets carrying the signal, only 4 wires. There are all kinds of shared wiring schemes that could work either way (constant enable VS switched on/off enable) but rather than getting too technical, a simple example of does the XYZ immediately lock on power on, tells me what I need to know about the system.

็Hi Jetguy,

I will check it out for you next week as I want to know as well if stepper drivers are upgradable or not.

When power on, the stepper motors for XY hold its position and can not move by hand till disabled it on the touchscreen. I didnt try to move Z by hand so I am not sure for that.

Here are the photos of the bottom of the Pro2.

Another thing that I notice is that the metal purge rods that come in accessories box can not get through the extruder gear from the top unlike the upgrade Bontech used on N2 so there might be some change in dimension of the extruder design.

I saw the ribbon cable has been changed Image

WOW, off-board dedicated stepper drivers!

Are you talking about replace the loud exhaust fan being replaced or are you talking about the hot end fans.

To me the exhaust fan is very loud and I wonder if it can be replaced. How worried do I need to be about getting the same specs?

Have you had any problems so far? I am having issues with heating that are eerily similar to the N series printer ribbon cable fiasco. I know they do to use the same cable but I am experiencing the same erratic temperature problems, except this time I get no error just burnt filament!

If you could, taking a couple of pictures and then running a simple test would test the safety.
#1 Can you take a good picture of the new extruder head breakout board? From what I have seen it changed to a newer version because of location of the large 3 wire heater connector compared to the old version.
Again, just a head on shot so we can better see the details of this board.

#2 For the test, the easier way is probably unplug down at the mainboard, but simply unplug the ribbon cable with the printer in the off state, turn it on, that in theory produces an error message.
#3 The next test requires plugging the cable back in (again, while the printer is off), then unplugging the cable after the printer is fullly booted and running.

I want to make it clear, please do not have a heat point set and be heating during this test. This is for safety. Unplugging a cable during operation should be no different than the cable failing during operation from a safety or user standpoint.
I would do it, but I don't have a new Pro2 and they won't yet sell the parts.

Also, while on Pro2 specific improvements over N series, is anyone with a Pro2 using the Ethernet port?
Can you confirm transfer rates and other connection related details using Ethernet to show that this is a fixed or improved specific detail of the Pro2?

Here are some pictures, as you can see they have done away with the ribbon cables. And sorry I am not using the Ethernet port for transfers.
