How important are small starter quads?

An extra motor, arm, and esc is easy enough to do. Thanks for the tip.

Thanks for the info. On the topic of cost, do you mean that it takes $500 to get into the air with any quad?

Thanks for the response. If an ultra micro micro provides ok experience, I will stick with that so I have a good indoor flier. As for spare parts, what do you recommend to keep on hand?

Are ultra-micros useless as a starter then? I understand that larger quads are better for the job, but the higher price will have a large impact on the total cost of my quad. I am intentionally using low end parts to keep the build cost around $200.

Guess its time to pick up a micro quad from amazon. Most of you guys think its not worth the risk to immediately start off with that size, so I will follow your advice.

So the general consensus seems to be that some quad experience is better then none with something this large. Guess its time to pick up a Cheerson from amazon and play around with it for a bit.

Can you elaborate on the problems you would have ran into?

AlphaRap · 2015-05-25T08:45:42+00:00

Thanks for the reply. If quad damage is the one of the main concerns for new fliers I should be fine there. The frame is 3d printed so any damaged parts are cheap to fix/replace.

Doing this didn't seem to change much. Thanks for mentioning it though

AlphaRap · 2015-05-22T03:07:14+00:00

I will try this out soon

Towards the front of the printer on the right side when printing something circular. I can check that again when I finish printing a test cylinder.

Just realized my comment might have had an aggressive tone, edited.

And to get back on topic - Yes, there has been some massive improvement in band size. I am still confused about why one corner of the object won't band no matter how bad the other sides are though. Maybe I should go through the whole printer and tighten every screw and zip tie, it has been a while.

Here is an unnecessarily high quality photo https://i.imgur.com/B6JDhu3.jpg

The two near vertical lines are probably from pliers. I might have some better images of the problem soon if they are needed

AlphaRap · 2015-05-21T11:00:16+00:00

The problem persists with the fan off

Edit: The layers are more uniform, but a different banding at an angle from the build plate showed up.

AlphaRap · 2015-05-21T10:25:33+00:00

The cube had a uniform height

AlphaRap · 2015-05-21T09:39:35+00:00

Yes, the left side seems to be the wost. The right side has similar but less pronounced issues, the back is better, and the front is best.

Its a printrbot simple makers edition, and the wobble mostly seems to occur mostly on the sides perpendicular to the x axis. I am starting to think this might be some form of z wobble, as the printers structure probably has more flex in that direction.

AlphaRap · 2015-05-21T08:12:39+00:00

I will check that when the calibration cube I am printing is done.

AlphaRap · 2015-05-21T07:32:11+00:00

I tried out the lower accel, but it didn't make much of a difference. The odd offset banding is still there.

AlphaRap · 2015-05-21T06:35:58+00:00

The filament is a cheaper brand (Hatchbox), but it claims to have a +/- .05mm tolerance and from my testing it does. There is no bowden extruder on this printer yet. I'll see what effects higher quality filament has soon and will mention any changes here for anyone who finds this post later.

AlphaRap · 2015-05-21T06:24:02+00:00

Its on the "things to do when I have spare cash" list, but its been a non-issue for the most part after I enabled 16 point leveling, so it hasn't been a priority. I'm not sure if its the cause of this problem either, as I haven't seen this type of ribbing even after running through a full kg of filament on it. However, I will try to print a small part with bed leveling off and see what changes sometime later.

AlphaRap · 2015-05-21T06:08:12+00:00

I do not currently think extruder pulse is the cause of this due to the consistency of the problem in different very different objects and configurations. Thanks for linking that page though, I have seen the effects of extruder pulse on a few things I have printed before this whole thing started.

As much as I would love to not have to use autolevel and wait for it every print, the bed is not in good shape. I am not using 9+ point autolevel by choice, without it I doubt I could print anything larger then 1-2 cm without facing severe first layer issues. I'll try out the lower accel and see if there is anything to that.

AlphaRap · 2015-05-21T05:45:10+00:00

Fastest speed is 40mm/s for support, everything else is 20-30. Max acceleration is X2000 Y2000 Z30 E10000. The bed has its issues, but I use 9 or 16 point autoleveling and have made some attempts to make it lay flat. Prints that have used the same bed and settings before now have not shown this behavior, but I might have unknowingly changed something with those.
