Australia and Japan

Perthian here: They actually sent me a tracking number. Thank god.

Delivery expected on the 21st by TNT.

 

Is the heated bed on? Should be for ABS prints.

Also, make sure you've levelled the Z axis?

 

You should start by using PLA and not ABS. Less variables you need to control.

I was hoping to start with PLA, that's what I was going to use the sample for (I bought a few spools of ABS about 6 months ago), but unfortunately my printer came with NO filament. Also it had the american Power cable and I have already had to do the Relay Mod to get the heated bed to stay on.

Shock horror I am still not that impressed by the Robo Team: months of delays, additional shipping costs and I still have to do a mod to get basical functionality on the 2nd day due to poor design. At least I have a functional printer now though.

 

Ziggy, yes. Because printing with PLA versus ABS is essentially identical except you add some additional variables, such as the bed temperature.

 

Finally got mine no sample filament , but they gave me a heated bed so can't really complain plus already have some filament anyways so I'm happy ​

 

Printer arrived today. Glass not broken, and sample filament present. I think I won.

 

got mine, with about a metre of pla. should have preplanned as now i cant do zip till i get some filament.
only unboxed to check for breakages. thankfully double boxed as the courier dropped it on the floor when he came in.

 

Arrived

Broken

i think

 

That looks like the cable management thingy is a little bent, that's all?

Tried running it?

 

I'm not at home to check mine, but I think he might have been talking about what could be a snapped part at the base of the non-threaded rod. Can't remember what it looks like.

 

No i think the black plastic support piece for the smooth z axis rod is snapped where it goes from the block looking piece to the tube.

 

That smooth rod support is definitely broken.

Begin rant for my fellow countrymen in OZ.....

I was shocked by some of the major flaws in the printer, that smooth rod support is so weak, i can break it with my mind.

I'm basically rebuilding my printer slowly before really getting much use out of it. New wider 15mm acetal base board and y-axis sliders, machined delrin vertical rod supports etc, E3D hotend, going all out basically.

I'm still impressed with the value, and the community this product comes along with, but geez, you can tell these guys are beginner engineers and rushed some of the design out.

My mods are going to be expensive because I'm just like that, but only a few dollars more in the initial production cost would have made this printer perfect... It's great that they have kept an open source attitude, but i think they should have consulted a few professionals before committing to the design when they got so much backer money.

The entire top moulding basically does nothing, it doesn't support anything, nada, and would have been the most expensive tool to cut and part to inject, plus its an awful beige colour, bloody hell, haven't you guys heard of PMS cool grey 8?

Rant over for now. I Still love my robo 3D.

 

Feel your pain Peter, I am in two minds about the whole thing. On one side it is still quite a lot of printer for the price, and a good introduction to in inner workings while I fix/mod stuff but on the other hand pretty disappointed that I did not receive a working printer for my money.

Already I have spend $60 installing a relay because the bed would turn off after about 5 mins. Now it stays on but due to another design flaw the bed drops 10-15deg after a couple of minutes so I still can't get prints (ABS) to stick. That and the bed is warped I think.

Several little things that I want to mod which I am surprised weren't thought of in the design too. First up is an adapter to make the z-axis limit switch actually hit the end of the lever. Pretty unreliable homing (not helped by the warped bed). I think next up will be what you identified, the smooth rod supports. Either that or a replacement for the (obviously afterthought) spool holder.

As I said, I'm in the same boat. I am still a fan of the machine, but I suspect there will be more rants in the future.

 

I think the thermocouple/thermister on the bottom of the bed could be partly to blame, that type of thermo couple isnt ideal for surface mounting to a flat piece of glass, its just held in contact (almost no surface area) with kapton tape on mine.

I'm going to 'glue' it to the glass with some hi-temp epoxy (muffler repair compound or similar) at some stage.

Even just a blob of window silicone will be much better, as long as the thermistor is still touching the glass.

 

What concerns me, since I have not received my printer yet, is that Robo is not adding these fixes for future printers sales.

It's just like that Microsoft mentality where MS sends out a their software into the world and wait for users to let them know what the bugs are and then charges those users for a working upgrade.

If only it were. Another User (Ziggy) with the same issue monitored the temp with an IR thermometer. Investigation into it is still under way. At least the Robo3D team are looking into it as well though.
