Sorry for the late reply.
I will prepare it and sent out the sample of L502 before this Wednesday. May I prepare some with other customer’s artworks for you?
If you would like to have L502 has showing cup function that is possible to do it but it will be additional tooling cost and adjustment cost.
You may also add me on wechat “joshlai505” that might be easier for you to contact me directly.
Thank you and please feel free to contact me anytime if you have any questions.
