[Bad PVA or user error?]

Can you recommend a humidity sensor? I'm going to try the above suggestions. In regard to the actual printing of the PVA. the standard settings should be fine? There are no major adjustments that need to be made?

Thanks

Thank you, I had a feeling it was more of a material issue. Do any of you use the dehumidifier storing stations?

[Bad PVA or user error?]

Good afternoon everyone, I am a teacher new to 3D printing and I am having trouble with the support material. I have been able to pick most things up very quickly but the ability to print with support is killing me. I have had prints where the first layer of PVA lays down nice and progressively gets worse,  then other times the pva material will come out clumpy or not even extrude. I have tried messing with the speed and temp to no avail. I am printing on the ultimaker3 and using ultimaker material and attempting to print with a 0.4 head with both materials. I was starting to think it is just poor PVA material, but I have opened a brand new package and had the same results, so I'm thinking I am missing something on the settings?

I have attached the file and photo. Any help is greatly appreciated. If there was a previous post on this somewhere maybe a moderator could share or point tme in the right direction. Thanks in advance.
